Bis(4-aminobenzenesulfonato-κN)diaquabis(dimethylformamide-κO)nickel(II) dihydrate

In the title compound, [Ni(C6H6NO3S)(2)(C3H7NO)(2)(H2O)(2)]center dot 2H(2)O, the Ni-II ion (site symmetry (1) over bar) is coordinated by two - NH2 groups from two 4-aminobenzenesulfonate anions, two O atoms from two dimethylformamide molecules and two water molecules, forming a slightly distorted trans-NiN2O4 octahedral geometry. In the crystal structure, intermolecular O-H center dot center dot center dot O, O-H center dot center dot center dot(O,O) and N-H center dot center dot center dot O hydrogen bonds link the components into a three- dimensional network. The O atoms of the sulfonate group are disordered over two sets of sites in a 0.833 (4):0.167 (4) ratio and the O atom of the uncoordinated water molecule is disordered over two sites in a 0.637 (18):0.363 (18) ratio.
