title: Bis(4-amino-benzene-sulfonato-κN)diaqua-bis(dimethyl-formamide-κO)nickel(II) dihydrate.
abstract: In the title compound, [Ni(C(6)H(6)NO(3)S)(2)(C(3)H(7)NO)(2)(H(2)O)(2)]·2H(2)O, the Ni(II) ion (site symmetry ) is coordinated by two -NH(2) groups from two 4-amino-benzene-sulfonate anions, two O atoms from two dimethyl-formamide mol-ecules and two water mol-ecules, forming a slightly distorted trans-NiN(2)O(4) octa-hedral geometry. In the crystal structure, inter-molecular O-H⋯O, O-H⋯(O,O) and N-H⋯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 mol-ecule is disordered over two sites in a 0.637 (18):0.363 (18) ratio.
