Diaqua-bis-(propane-1,3-diamine)-copper(II) bis-[diamminetetra-kis-(thio-cyanato-κN)chromate(III)] dimethyl sulfoxide octa-solvate.

ABSTRACT: The ionic title complex, [Cu(C(3)H(10)N(2))(2)(H(2)O)(2)][Cr(NCS)(4)(NH(3))(2)]·8C(2)H(6)OS, consists of complex [Cu(dipr)(2)(H(2)O)(2)](2+) copper cations (dipr is propane-1,3-diamine), complex [Cr(NCS)(4)(NH(3))(2)](-) anions and uncoord-inated solvent dimethyl sulfoxide (DMSO) mol-ecules. All the metal atoms lie on crystallographic centers of symmetry. The cations are connected to the anions through N-H⋯O hydrogen bonds between the NH(3) mol-ecules of the anion and the water mol-ecules of the cation. The DMSO mol-ecules are involved in hydrogen-bonded linkage of the [Cr(NCS)(4)(NH(3))(2)](-) anions into supra-molecular chains through bridging O atoms. A network of hydrogen bonds as well as short S⋯S contacts [3.5159 (12) and 3.4880 (12) Å] between the NCS groups of the complex anions li
