The title compound, [Cu(SO4)(C12H8N2)2]·C4H10O2, is comprised of neutral monomeric complex and butane-2,3-diol solvent molecules. In the complex, the CuII ion is in a distorted square-pyramidal coordination environment defined by four N atoms from two chelating 1,10-phenanthroline ligands and one O atom from a monodentate sulfate anion; the O atom is at the apex. The two chelating N2C2 groups subtend a dihedral angle of 85.8 (4)°. In the crystal, the neutral monomeric complex and butane-2,3-diol solvent molecules are held together by O—HO hydrogen bonding, which leads to additional stabilization of the structure. The presence of pseudosymmetry in the structure suggests the higher symmetry space group C2/c, but attempts to refine the structure in this space group resulted in an unsatisfactory model and high R and wR values. The sulfate anion is disordered over two sets of sites with occupancies of 0.55 (1) and 0.45 (1).
