Tetra-kis(μ-acetato-κ(2)O:O')-bis-[(3-pyridine-carboxaldehyde-κN')]dicopper(II)(Cu-Cu).

The binuclear title compound, [Cu(2)(CH(3)CO(2))(4)(C(6)H(5)NO)], is located about a center of inversion. The Cu(II) atoms are connected [Cu-Cu = 2.6134 (5) Å] and bridged by four acetate ligands. Their distorted octa-hedral coordination geometry is completed by a terminal pyridine N atom of a 3-pyridincarboxaldehyde ligand. In the crystal, the complex mol-ecules 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 supra-molecular architecture.
