Bis(1,10-phenanthroline-[kappa]2N,N')(sulfato-O)copper(II) propane-1,3-diol monosolvate

Abstract: In the title compound, [Cu(SO4)(C12H8N2)2]·C3H8O2, the CuII ion is bonded to two chelating 1,10-phenanthroline (phen) ligands and one O atom from a monodentate sulfate ligand in a distorted square-based pyramidal arrangement, with the O atom in a basal site. The two chelating N2C2 groups subtend a dihedral angle of 71.10 (15)°. In the crystal, the solvent molecule forms two O-H...O hydrogen bonds to its adjacent complex molecule. The chosen crystal was found to be a racemic twin; 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.
