【 摘 要 】

In the title complex, [Ni(SO4)(C5H8N2)3(H2O)2], the NiII ion is coordinated by three facial 1-ethyl-1H-imidazole ligands, one monodentate sulfate ligand and two water mol­ecules in a slightly distorted octa­hedral coordination environment. In the crystal, two pairs of O—H⋯O hydrogen bonds link complex mol­ecules, forming inversion dimers incorporating R24(8), R22(8) and R22(12) rings. The dimeric unit also contains two symmetry-unique intra­molecular O—H⋯O hydrogen bonds. In addition, weak C—H⋯O hydrogen bonds, weak C—H⋯π inter­actions and π–π inter­actions with a centroid–centroid distance of 3.560 (2) Å combine to form a three-dimensional network. One of the ethyl groups is disordered over two sets of sites with occupancies in the ratio 0.586 (7):0.414 (7).
