Bis(1,10-phenanthroline-κ2 N,N′)(sulfato-O)copper(II) ethane-1,2-diol monosolvate

In the title compound, [Cu(SO4)(C12H8N2)2]·C2H6O2, the CuII 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.

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
