Aqua{N-[(4-methylphenyl)sulfonyl]glycinato(2−)-κ2N,O}(1,10-phenanthroline)copper(II)

In the title complex, [Cu(C9H9NO4S)(C12H8N2)(H2O)], the CuII ion is coordinated in a distorted square-pyramidal geometry by the two N atoms from a 1,10-phenanthroline ligand, one N atom from the deprotonated amino group of an N-tosylglycinate ligand, one O atom from the carboxylate part of the N-tosylglycinate ligand and a water O atom. Intermolecular O—H...O hydrogen bonds involving the water H atoms link neighboring molecules into supramolecular chains along [010]. Weak π–π stacking interactions [centroid–centroid distances of 3.456 (1) and 3.691 (1) Å] between the benzene rings of 1,10-phenanthroline ligands of adjacent molecules extend the chains into a layer structure parallel to (001).
