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

摘要

In the title compound, [Ni(C6H6NO3S)2(C3H7NO)2(H2O)2]·2H2O, the NiII ion (site symmetry ) 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⋯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 mol­ecule is disordered over two sites in a 0.637 (18):0.363 (18) ratio.
