Tetrakis(μ-acetato-κ2 O:O')-bis[(3- pyridinecarboxaldehyde-κN')]dicopper(II)(Cu-Cu)

Abstract

The binuclear title compound, [Cu2(CH3CO2)4(C6H 5NO)], is located about a center of inversion. The CuII atoms are connected [Cu-Cu = 2.6134(5)Å] and bridged by four acetate ligands. Their distorted octahedral coordination geometry is completed by a terminal pyridine N atom of a 3-pyridincarboxaldehyde ligand. In the crystal, the complex molecules are linked by C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to the ab plane. These networks are linked via C-H⋯O hydrogen bonds involving inversion-related 3-pyridinecarboxaldehyde ligands, forming a three dimensional supramolecular architecture.
