title: Bis[N-(2-amino-eth-yl)ethane-1,2-diamine-κN,N',N'']copper(II) tris-[diamminetetra-kis-(thio-cyanato-κN)chromate(III)] thio-cyanate dimethyl sulfoxide tetra-deca-solvate monohydrate.
abstract: The ionic title complex, [Cu(C(4)H(13)N(3))(2)](2)[Cr(NCS)(4)(NH(3))(2)](3)(NCS)·14C(2)H(6)OS·H(2)O, consists of complex [Cu(dien)(2)](2+) cations [dien is N-(2-amino-eth-yl)ethane-1,2-diamine], com-plex [Cr(NCS)(4)(NH(3))(2)](-) anions, an NCS(-) counter-anion and uncoordinated dimethyl sulfoxide (DMSO) and water solvent mol-ecules. One of the Cr atoms lies on an inversion center, while the second Cr atom and the Cu atom lie in general positions. The thio-cyanate counter-anion and water mol-ecule are disordered over two positions close to an inversion center. There are several types of hydrogen-bond inter-actions present in the title compound, which connect the complex cations and anions into bulky [Cu(2)Cr(3)] polynuclear species. The four NH(3) groups of the complex anions and six bridging DMSO O atoms link the three complex anions via hydrogen bonding into the anionic polynuclear species [Cr(NCS)(4)(NH(3))(2)](3)·6DMSO. The last one is connected by four bridging DMSO O atoms with the two complex copper cations through N-H⋯ O hydrogen bonds between the terminal NH(3) groups of the anionic polynuclear species and the NH and NH(2) groups of the dien ligand. One additional DMSO mol-ecule is connected via hydrogen bonding to one of the terminal NH(3) groups of the anionic polynuclear species. Another DMSO mol-ecule is connected via hydrogen bonding to each Cu(dien)(2)](2+) cation.
