In the title compound, [Ni(SO4)(C12H8N2)2]·C4H10O2, the NiII ion is six-coordinated by four N atoms from two chelating 1,10-phenanthroline ligands and two O atoms from an O,O'-bidentate sulfate anion, resulting in a distorted octahedral geometry for the metal ion. The dihedral angle between the two chelating N2C2 groups is 83.82 (12)°. The NiII ion, the S atom and the mid-point of the central C-C bond of the butane-2,3-diol solvent molecule lie on a twofold rotation axis. In the crystal, the complex molecules and solvent molecules are held together by pairs of symmetry-related Odiol-HOsulfate hydrogen bonds involving the uncoordinating O atoms of the sulfate ions. The solvent molecule is disordered over two sets of sites with site occupancies of 0.450 (9) and 0.550 (9).
