Abstract: In the title compound, [Ni(C₆H₆NO₃S)₂(C₃H₇NO)₂(H₂O)₂]·2H₂O, the Ni^II ion (site symmetry $\\overline{1}$ ) 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-HO, O-H(O,O) and N-HO 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.
