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.
在标题化合物[Ni(C₆H₆NO₃S)₂(C₃H₇NO)₂(H₂O)₂]·2H₂O中，Ni(II)离子（位点对称性 ）由两个4-氨基苯磺酸盐阴离子的两个-NH₂基团、两个二甲基甲酰胺分子的两个O原子和两个水分子配位，形成略微扭曲的反式-NiN₂O₄八面体几何构型。在晶体结构中，分子间的O-H⋯O、O-H⋯(O,O)和N-H⋯O氢键将各组分连接成三维网络。磺酸根基团的O原子在两组位点上无序分布，比例为0.833 (4):0.167 (4)，未配位水分子的O原子在两个位点上无序分布，比例为0.637 (18):0.363 (18)。
