TETRAKIS(MU-BENZOATO-O-O')BIS(N,N-DIETHYLNICOTINAMIDE-N')DICOPPER(II)

The title molecule, [CU2(Cu6H5COO)(4)(C10H14N2O)(2)], is a crystallographically centrosymmetric binuclear complex, with Cu atoms [Cu...Cu' = 2.613 (1) Angstrom] bridged by four benzoate ligands. The four nearest O atoms around each Cu atom form a square-planar arrangement with the square-pyramidal coordination completed by the pyridine N atom of the N,N(-diethylnicotinamide ligand at a distance of 2.162(6) Angstrom. Each Cu atom is displaced by 0.190 (1) Angstrom from the plane of the four O atoms, with an average Cu-O distance of 1.974(6) Angstrom.
