Bis(1,10-phenanthroline-κ²N,N′)(sulfato-κ²O,O′)cobalt(II) propane-1,2-diol monosolvate

In the title compound, [Co(SO₄)(C₁₂H₈N₂)₂]·C₃H₈O₂, the Co^II atom (site symmetry 2) has a distorted octa­hedral coordination composed of four N atoms from two chelating 1,10-phenanthroline ligands and two O atoms from an O,O′-bidentate sulfate ligand, in which the S atom has site symmetry 2. The dihedral angle between the two chelating N₂C₂ groups is 84.46 (15)°. The complex and solvent mol­ecules are connected through O—H...O hydrogen bonds. The solvent mol­ecule is equally disordered over two positions and is also located on a twofold axis.

Bis(1,10-phenanthroline-κ²N,N′)(sulfato-O)copper(II) butane-2,3-diol monosolvate

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 Cu^II 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—H...O 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).
