An unusual half-open cubane-like tetranuclear copper(II) complex supported by both μ-alkoxo and μ3-hydroxo bridges: Structure, magnetic properties, EPR and DFT studies

Thioether sulfur-bound [Cu2] complexes showing catechol oxidase activity and DNA cleaving behaviour

Ligand backbone alteration leads to different mechanisms for catecholase activity and order of interaction with DNA molecules.

A family of [Cu2], [Cu4] and [Cu5] aggregates: alteration of reaction conditions, ancillary bridges and capping anions

Enforced coordination by NO₃⁻, ClO₄⁻ and CF₃COO⁻ groups resulted in the formation of [Cu₂] (1), [Cu₄] (2) and [Cu₅] (3) complexes using H₅L1.

The synthesis, structure, topology and catalytic application of a novel cubane-based copper(II) metal-organic framework derived from a flexible amido tripodal acid

A novel chiral metal-organic framework, [Cu4(HL)2(H2O)4(MeO)4]n (), has been successfully synthesized from a tripodal flexible ligand (2S,2'S,2''S)-2,2',2''-(benzenetricarbonyltris(azanediyl))tripropanoic acid (H3L). Compound was characterized by IR and X-ray powder diffraction analysis. The structure was determined by X-ray single crystal diffraction analysis revealing that possesses a 3D network, featuring a tetranuclear cubane-type secondary building block [Cu4(MeO)4](4+), formed via the connection of four metal ions to four methoxide ions. These secondary building blocks are linked by four different HL(2-) ligands to construct a porous three dimensional framework of the dia topology with one-dimensional channels. Compound also acts as a heterogeneous catalyst for the diastereoselective nitroaldol (Henry) reaction, providing high yields (up to 91%) and good diastereoselectivities under ambient conditions. This catalyst can be recycled without significant loss of activity.
