Bis(1,10-phenanthroline-κN,N')(sulfato-κO,O')nickel(II) propane-1,3-diol solvate.

In the structure of the title compound, [Ni(SO(4))(C(12)H(8)N(2))(2)]·C(3)H(8)O(2), the Ni(II) ion (site symmetry 2) is six-coordinated in a distorted octa-hedral manner by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and two O atoms from a bidentate sulfate ligand (2 symmetry). The dihedral angle between the two chelating NCCN groups is 80.9†(1)°. The central C atom of the propane-1,3-diol solvent mol-ecule is likewise located on a twofold rotation axis. In the crystal structure, the [Ni(SO(4))(C(12)H(8)N(2))(2)] and C(3)H(8)O(2) entities are connected through inter-molecular O-H⋯O hydrogen bonding.
