Aquachloro(1,10-phenanthroline-kappa 2N,N')(p-toluenesulfonato-kappa O)copper(II).

In the title compound, [CuCl(C(7)H(7)O(3)S)(C(12)H(8)N(2))(H(2)O)], the central Cu atom is coordinated by a water molecule, a chloride ion, an O-monodentate p-toluenesulfonate anion and an N,N'-bidentate 1,10-phenanthroline ligand. The copper environment is best described as a slightly distorted square pyramid, with bond distances Cu-Cl 2.2282 (9) A, Cu-OW 1.
