Bis{μ-2,2′-[o-phenyl­enebis(nitrilo­methyl­idyne)]diphenolato}dicopper(II) N,N′-dimethyl­formamide disolvate

The title compound, [Cu(2)(C(20)H(14)N(2)O(2))(2)]·2C(3)H(7)NO, consists of a centrosymmetric dimer composed of two copper(II) ions and two tetra­dentate salphen ligands {H(2)salphen is 2,2′-[o-phenyl­enebis(nitrilo­methyl­idyne)]diphenol}, and two dimethyl­formamide solvent mol­ecules. The Cu(II) 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 π–π inter­actions [centroid-centroid distance 3.779 (2) Å] and C—H⋯O hydrogen bonds.
