-2,2'-[o-phenylenebis(nitrilomethylidyne)]diphenolato}dicopper(II) N,N'-dimethylformamide disolvateAbstract: The title compound, [Cu2(C20H14N2O2)2]·2C3H7NO, consists of a centrosymmetric dimer composed of two copper(II) ions and two tetradentate salphen ligands {H2salphen is 2,2'-[o-phenylenebis(nitrilomethylidyne)]diphenol}, and two dimethylformamide solvent molecules. The CuII atom is bonded to two N imino atoms and three phenolate O atoms of salphen. One deprotonated phenol group of each ligand bridges two Cu atoms, forming the dimer. The geometry about the five-coordinate Cu atom can best be described as slightly distorted rectangular pyramidal. The crystal structure is stabilized by ![[pi]](/logos/entities/pi_rmgif.gif)
