F. Xu, W. You and W. Huang

Abstract: The title compound, [Cu(C₁₀H₈N₂)₃]SO₄·7.5H₂O, is a six-coordinate copper(II) complex with a slightly elongated octahedral coordination geometry. The pyridyl rings of the three bipyridyl ligands are not coplanar, making dihedral angels of 9.5 (5), 5.2 (4) and 5.8 (5)°. In the crystal, several O-HO and C-HO hydrogen-bonding interactions are observed due to the existance of a large number of water molecules and the sulfate dianions.
