(2,2′-Bipyridine-κ2N,N′)hydroxido[N-(4-tolylsulfonyl)alaninato-κ2N,O1]copper(II) hemihydrate

In the title complex, [Cu(C10H12NO4S)(OH)(C10H8N2)]·0.5H2O, the Cu(II) ion shows a distorted square-pyramidal coordination geometry with two N atoms from the 2,2′-bipyridine ligand and one N and one O atom from the N-tosyl-α-alaninato ligand forming the basis of the coordination polyhedron and another O atom of the hydroxo group acting as the apex of the pyramid. The solvent water molecule is statistically disordered over two positions.
