Diaqua­bis­(propane-1,3-diamine)­copper(II) bis­[diamminetetra­kis­(thio­cyanato-κN)chromate(III)] dimethyl sulfoxide octa­solvate

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 uncoord­inated solvent dimethyl sulfoxide (DMSO) mol­ecules. 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) mol­ecules of the anion and the water mol­ecules of the cation. The DMSO mol­ecules are involved in hydrogen-bonded linkage of the [Cr(NCS)(4)(NH(3))(2)](−) anions into supra­molecular 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 link the mol­ecules into a three-dimensional supra­molecular network.
