Bis(1,10-phenanthroline-κ2N,N′)(sulfato-κ2O,O′)nickel(II) ethane-1,2-diol solvate

In the title compound, [Ni(SO4)(C12H8N2)2]·C2H6O2, the coordination polyhedron around the Ni2+ ion is a distorted octahedron, with four N atoms from two phenanthroline groups and two O atoms from a bidentate sulfate ligand. The Ni2+ ion lies on a special position of site symmetry 2. Intermolecular O—H...O hydrogen bonds help to stabilize the structure. The OH group of the ethane-1,2-diol solvent is disordered over two positions with equal occupancy.
