Bis(1,10-phenanthroline-κ2N,N′)[2-(4-sulfonatoanilino)acetato-κO]copper(II) dihydrate

Abstract

In the title compound, [Cu(C8H7NO5S)(C12H8N2)2]·2H2O, the CuII ion is coordinated by four N atoms from two 1,10-phenanthroline (phen) ligands and one O atom from a 2-(4-sulfonatoanilino)acetate (spia) ligand in a distorted square-pyramidal geometry. Intermolecular N—H...O and O—H...O hydrogen bonds, as well as π–π interactions between phen ligands and between phen and spia ligands [centroid–centroid distances = 3.663 (3), 3.768 (3) and 3.565 (3) Å], result in a three-dimensional supramolecular structure.
