Bis(1,10-phenanthroline-κ(2) N,N′)(sulfato-O)copper(II) ethane-1,2-diol monosolvate

In the title compound, [Cu(SO(4))(C(12)H(8)N(2))(2)]·C(2)H(6)O(2), the Cu(II) ion is five-coordinated in a distorted square-pyramidal manner by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and one O atom from a monodentate sulfate anion. The four N atoms comprise a square and the one O atom the apex of a square pyramid. The two chelating N(2)C(2) groups are oriented at 71.1 (2)°. In the crystal, the components are connected by inter­molecular O—H⋯O hydrogen bonding. 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.
