title: Bis(1,10-phenanthroline-κN,N')[2-(4-sulfonato-anilino)acetato-κO]copper(II) dihydrate.
abstract: In the title compound, [Cu(C(8)H(7)NO(5)S)(C(12)H(8)N(2))(2)]·2H(2)O, the Cu(II) ion is coordinated by four N atoms from two 1,10-phenanthroline (phen) ligands and one O atom from a 2-(4-sulfonato-anilino)acetate (spia) ligand in a distorted square-pyramidal geometry. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, as well as π-π inter-actions 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 supra-molecular structure.
