Abstract
In a crystal, a pair of homoanions (Te(C6H5)Cl4-) are arranged in a parallel manner, close enough to interact with each other. Quantum chemical analysis indicates the existence of two strong noncovalent chalcogen bonds engaging the σ-hole of the chalcogen atoms from one unit and electron density accumulated on the Cl atom of the neighboring unit. In a solid, chalcogen bonds are supported by a multitude of HBs between interacting (Te(C6H5)Cl4-) anions and the C5H5NBr+ counterions. These studies are extended to the model homodimers [(Ch(CH3)X4)-]2, where Ch represents an atom of group 16 (S, Se, and Te) while X = Cl, Br, and I. In these model systems, the aromatic ring was replaced by a methyl group and the counterions were not included. The consequence of this is a different noncovalent bond network in comparison to the system in a solid (the absence of intermolecular HBs and the presence of dihalogen bonds). The tendency for more exoenergetic complexation increases in the Cl < Br < I series. The chalcogen size effect is much smaller. However, critical to the stability of this system is overcoming the Coulomb repulsion between the two monoanions. This is possible because of the polarizable environment that exists in the crystal due to the presence of counter ions.

Abstract
Inspection of the arrangement of tetrachloridopalladate(II) centers in a crystalline solid places the Cl of one [PdCl4]2- directly above the Pd center of its neighbor. A survey of the CSD provides 22 more examples of such MX42-⋯MX42- complexes, with M being a Group 10 metal and X = Cl, Br, or I. Quantum calculations attribute this arrangement to a π-hole bond wherein Cl lone pairs of one unit transfer charge to vacant orbitals above the Pd center of its neighbor. The stabilizing effect of this bond must overcome the strong Coulombic repulsion between the two dianions, which is facilitated by a polarizable environment as would be present in a crystal, but much more so when the effects of the neighboring counterions are factored in. These conclusions are extended to other [MX4]2- homodimers, where M represents other members of Group 10, namely Ni and Pt.

Abstract
The ability of two anions to interact with one another is tested in the context of pairs of TrX4- homodimers, where Tr represents any of the triel atoms B, Al, Ga, In, or Tl, and X refers to a halogen substituent F, Cl, or Br. None of these pairs engage in a stable complex in the gas phase, but the situation reverses in water where the two monomers are held together by Tr⋯X triel bonds, complemented by stabilizing interactions between X atoms. Some of these bonds are quite strong, notably those involving TrF4-, with interaction energies surpassing 30 kcal mol-1. Others are very much weaker, with scarcely exothermic binding energies. The highly repulsive electrostatic interactions are counteracted by large polarization energies.

Abstract
Molecules of the type XYT = Ch (T = C, Si, Ge; Ch = S, Se; X,Y = H, CH3, Cl, Br, I) contain a σ-hole along the T = Ch bond extension. This hole can engage with the N lone pair of NCH and NCCH3 so as to form a chalcogen bond. In the case of T = C, these bonds are rather weak, less than 3 kcal/mol, and are slightly weakened in acetone or water. They owe their stability to attractive electrostatic energy, supplemented by dispersion, and a much smaller polarization term. Immersion in solvent reverses the electrostatic interaction to repulsive, while amplifying the polarization energy. The σ-holes are smaller for T = Si and Ge, even negative in many cases. These Lewis acids can nonetheless engage in a weak chalcogen bond. This bond owes its stability to dispersion in the gas phase, but it is polarization that dominates in solution.

Abstract
Planar (HgCl3 )- anions are stacked fairly closely together in a slipped parallel arrangement within several crystal structures. Quantum chemical analysis shows evidence of strong noncovalent spodium bonds between the Hg π-hole of one unit and the Cl atom of an adjacent unit. Anion⋅⋅⋅anion spodium bonds work in tandem with crystal packing forces.

Abstract
The possibility that MX3- anions can interact with one another is assessed via ab initio calculations in gas phase as well as in aqueous and ethanol solution. A pair of such anions can engage in two different dimer types. In the bridged configuration, two X atoms engage with two M atoms in a rhomboid structure with four equal M-X bond lengths. The two monomers retain their identity in the stacked geometry which contains a pair of noncovalent MX interactions. The relative stabilities of these two structures depend on the nature of the central M atom, the halogen substituent, and the presence of solvent. The interaction and binding energies are fairly small, generally no more than 10 kcal mol-1. The large electrostatic repulsion is balanced by a strong attractive polarization energy.

Abstract
The ability of a TrCl4- anion (Tr = Al, Ga, In, Tl) to engage in a triel bond with both a neutral NH3 and CN- anion is assessed by ab initio quantum calculations in both the gas phase and in aqueous medium. Despite the absence of a positive σ or π-hole on the Lewis acid, strong triel bonds can be formed with either base. The complexation involves an internal restructuring of the tetrahedral TrCl4- monomer into a trigonal bipyramid shape, where the base can occupy either an axial or equatorial position. Although this rearrangement requires a substantial investment of energy, it aids the complexation by imparting a much more positive MEP to the site that is to be occupied by the base. Complexation with the neutral base is exothermic in the gas phase and even more so in water where interaction energies can exceed 30 kcal mol-1. Despite the long-range coulombic repulsion between any pair of anions, CN- can also engage in a strong triel bond with TrCl4-. In the gas phase, complexation is endothermic, but dissociation of the metastable dimer is obstructed by an energy barrier. The situation is entirely different in solution, with large negative interaction energies of as much as -50 kcal mol-1. The complexation remains an exothermic process even after the large monomer deformation energy is factored in.

Abstract
![]()
A central ZF3 molecule (Z = P, As, Sb, Bi) is allowed
to interact with a number of nucleophiles exemplified by NCH, NH3, and NC– anion. The Z···N
pnicogen bond (ZB) to a single base grows stronger for heavier Z atom:
P < A < Sb < Bi and follows the NCH < NH3 <
NC– order for the three bases. The maximum number
of ZBs depends on both the nature of the base and pnicogen atom. PF3 and AsF3 can pnicogen bond with only a single
CN–; SbF3 and BiF3 can interact
with two anions but only weakly. The weak NCH nucleophile can engage
in a maximum of two ZBs, while three ZBs occur for NH3.
The latter NH3 maximum can be extended to four ZBs but
only for BiF3. The fourth ZB is somewhat longer and weaker
than the others, and the entire (H3N)4···BiF3 complex relies partially on secondary interactions for its
stability.

Abstract
The ability of two NH3 ligands to engage in simultaneous chalcogen bonds to a hypervalent YF4 molecule, with Y = S, Se, Te, Po, is assessed via quantum calculations. The complex can take on one of two different geometries. The cis structure places the two ligands adjacent to one another in a pseudo-octahedral geometry, held there by a pair of σ-hole chalcogen bonds. The bases can also lie nearly opposite one another, in a distorted octahedron containing one π-hole and one strained σ-hole bond. The cis geometry is favored for Y = S, while Te, and Po tend toward the trans structure; they are nearly equally stable for Se. In either case, the binding energy rises rapidly with the size of the Y atom, exceeding 30 kcal mol-1 for PoF4.

Abstract
Density functional study has been performed for a new anticancer agent, cis-[PtCl2(NH3)(2-picoline)] (1), AMD473, now clinically tested. The molecular structure, natural charges, orbital occupancies, vibrational frequencies and metal-ligand stretching force constants were calculated using the modified Perdew-Wang functional (mPW1PW) with the combined D95V(d,p) and LANL2DZ basis set. For comparison, analogous calculations were performed for: cis-[PtCl2(NH3)(3-picoline)] (2), cis-[PtCl2(NH3)(pyridine)] (3) and cisplatin. The interesting structural feature of 1 is almost perpendicular orientation of the 2-picoline ligand with respect to the molecular plane. In the remaining complexes, 2 and 3, the tilt of the pyridine ring is smaller. The position of the methyl group in 1 introduces steric hindrance to an axial approach of the Pt metal. The natural bond analysis (NBO) has provided detailed insight into the electronic donor-acceptor interactions within the platinum coordination sphere. The results clearly indicate that the Pt-N(py) bond is stronger than Pt-NH3 bond, and the Pt-Cl bond trans to 2-picoline is weaker than the cis Pt-Cl bond. Thus, both the trans effect of the 2-picoline ligand and a steric hindrance of Pt in 1 can be of key importance in the different mode of binding of this drug to DNA, in comparison with cisplatin.
