In the title compound, [Ni(C7H4N3O2)2(C12H8N2)2]·CH3OH, the NiII atom is six-coordinated in a distorted N6 octa­hedral geometry and is chelated by two phenanthroline ligands and two phenyl­cyanamide groups which occupy cis positions. The (4-nitro­phen­yl)cyanamide anions act as monodentate ligands. There is one classical inter­molecular O—H⋯N hydrogen bond and several C—H⋯O hydrogen bonds are also observed.
