title: [N,N,N',N'-Tetra-kis(benzimidazol-2-yl-meth-yl)ethane-1,2-diamine]copper(II) sulfate monohydrate.
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).
