چکیده
The asymmetric unit of the title compound, [Ni(C(2)H(6)N(4)O(2))(3)]SO(4)·5H(2)O, contains two complex cations, two sulfate anions and ten lattice water mol-ecules. In both independent cations, the central Ni(II) ion adopts a distorted octa-hedral coordination involving six imino N atoms of three bidentate oxamide dioxime ligands. The bulk structure is achieved by a three-dimensional network of O-H⋯O and N-H⋯O hydrogen bonds which inter-link the ionic partners and some water mol-ecules in such a manner that the lattice framework thus formed defines channels parallel to [100]. The other water mol-ecules are lodged inside these channels. Two of the ten water mol-ecules in the asymmetric unit are disordered over three sites, in 0.356 (3):0.324 (5):0.320 (5) and 0.247 (3):0.293 (6):0.460 (6) occupancy ratios, and one O atom of a sulfate ion is also disordered over two sites, with occupancies of 0.621 (5) and 0.379 (5).
