Bis(1,10-phenanthroline-kappa N-2,N ')(sulfato-kappa O-2,O ')nickel(II) propane-1,2-diol monosolvate

In the title compound, [Ni(SO4)(C12H8N2)(2)]center dot C3H8O2, the Ni-II atom exhibits a distorted octahedral coordination by four N atoms from two chelating 1,10-phenanthroline ligands and two O atoms from an O,O '-bidentate sulfate group. A twofold rotation axis passes through the Ni and S atoms and the midpoint of the hydroxyl C-C bond of the propane-1,2-diol solvent molecule. The dihedral angle between the two chelating N2C2 groups is 85.61 (8)degrees. The [NiSO4(C10H8N2)(2)] and propane-1,2-diol units are held together by a pair of symmetry-related intermolecular O-H center dot center dot center dot O hydrogen bonds involving the uncoordinating O atoms of the sulfate ion. Due to symmetry, the solvent molecule is equally disordered over two positions.
