title: Bis{μ-2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenolato}dicopper(II) dimethyl sulfoxide disolvate.
abstract: The title compound, [Cu(2)(C(18)H(19)N(3)O(2))(2)]·2C(2)H(6)OS or [Cu(2)(SalenN(3)H)(2)]·2DMSO, where SalenN(3)H is the multidentate Schiff base 2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenolate dianion and DMSO is dimethyl sulfoxide, is a solvated dinuclear Cu(II) complex. The neutral complex is built from two Cu(SalenN(3)H) units related by an inversion center. All heteroatoms in the Schiff bases coordinate the Cu(II) ions, which display highly distorted trigonal bipyramidal geometries. The solvent mol-ecules are located in the structural voids of the complex and are disordered over two positions with occupancies of 0.642 (15) and 0.358 (15). The previously characterized acetone disolvate of the same complex presents identical mol-ecular and crystal structures, and crystallizes with cell parameters very close to those of the DMSO disolvate reported here.
