Crystal structure, ferromagnetostructural behavior and evidence of cooperative Jahn–Teller interactions of the complex [CuL]Cl·H2O (L=N-glycyl-2(aminomethyl)benzimidazol), synthesized by a novel simple method of peptide bond formation

mer-(3,5-Dichloro-2-oxidobenzaldehyde thio-semicarbazonato-κS,N,O)(methanol-κO)(1,10-phenanthroline-κN,N')nickel(II)

In the title compound, [Ni(C₈H₅Cl₂N₃OS)(C₁₂H₈N₂)(CH₃OH)], the Ni^II atom is octa­hedrally coordinated by one N, one O and one S atom from a 3,5-dichloro-2-oxidobenzaldehyde thio­semicarbazonate ligand, another O atom from methanol and another two N atoms from 1,10-phenanthroline. The crystal structure is constructed by N—H⋯Cl, N—H⋯N, C—H⋯S and O—H⋯S hydrogen bonds.

{2-[(3,5-Dichloro-2-oxidobenzyl-idene)amino-κN,O]-3-methyl-penta-noato-κO}(N,N'-dimethyl-formamide-κO)copper(II)

In the title compound, [Cu(C₁₃H₁₃Cl₂NO₃)(C₃H₇NO)], the Cu^II atom is coordinated in a slightly distorted square-planar geometry by two O atoms and one N atom from the tridentate chiral ligand 2-[(3,5-dichloro-2-oxidobenzyl­idene)amino]-3-methyl­penta­noate and by one O atom from dimethyl­formamide. In the crystal structure, the Cu atom forms contacts with Cl and O atoms of two units (Cu⋯Cl and Cu⋯O = 3.401 and 2.947 Å, respectively), thereby forming an approximately octa­hedral arrangement. A three-dimensional network is constructed through Cl⋯Cu, O⋯Cu, Cl⋯Cl contacts and C—H⋯O hydrogen bonds.

(3,5-Dichloro-salicylaldehyde thio-semi-carbazonato-κS,N,O)(N,N'-dimethyl-formamide-κO)copper(II) dimethyl-formamide solvate

In the title compound, [Cu(C₈H₅Cl₂N₃OS)(C₃H₇NO)]·C₃H₇NO, the Cu^II atom is coordinated in a slightly distorted square-planar geometry by an O, an S and an N atom from the tridentate ligand 3,5-dichloro­salicylaldehyde thio­semi­carb­azonate ligand and one O atom from dimethyl­formamide. At the same time, the Cu atom is in contact with S and Cl atoms from another two complexes [Cu⋯S and Cu⋯Cl = 2.9791 (2) and 3.3800 (3) Å, respectively], thereby forming a [4 + 2] coordination geometry. The crystal structure exhibits N—H⋯O and N—H⋯N hydrogen bonds.
