ABSTRACT: In the title compound, [Cu(C(34)H(32)N(10))]SO(4)·H(2)O, the Cu(II) ion is coordinated by six N atoms of a hexa-dentate N,N,N',N'-tetra-kis(benzimidazol-2-ylmeth-yl)ethane-1,2-diamine (EDTB) ligand, in a distorted octa-hedral environment. In the crystal structure, inter-molecular N-H?O and weak C-H?O hydrogen bonds connect the cations, anions and water mol-ecules into a three-dimensional network. The O atoms of the anion are disordered over two sites with refined occupancies of 0.711?(2) and 0.289?(2).

N,N,N',N'-Tetra-kis(2-hy-droxy-5-methyl-benz-yl)ethane-1,2-diamine dimethyl-formamide disolvate.

Project description:The title compound, C(34)H(40)N(2)O(4)·2C(3)H(7)NO, was synthesized by the Mannich condensation of ethane-diamine, formaldehyde and p-cresol. In the crystal, the tetra-phenol mol-ecule is arranged around an inversion center. The mol-ecule and the dimethyl-formamide solvate are linked through an O-H?O hydrogen bond. An intra-molecular O-H?N hydrogen bond occurs in the tetra-phenol mol-ecule, which may influence the mol-ecular confomation. Futhermore, C-H?O and ?-? stacking inter-actions [centroid-centroid distance = 3.7081?(14)?Å] stabilize the crystal packing, building a three-dimensional network.

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.
