Aquabis(2-iodoacetato-κO)(1,10-phenanthroline-κ2N,N′)copper(II)

Abstract

In the title compound, [Cu(C2H2IO2)2(C12H8N2)(H2O)], the CuII ion is coordinated by two N atoms [Cu—N = 2.013 (4) and 2.024 (4) Å] from a 1,10-phenanthroline ligand and three O atoms [Cu—O = 1.940 (4)–2.261 (4) Å] from two carboxyl ligands and a water molecule in a distorted square-pyramidal geometry. One iodoacetate O atom [Cu—O = 2.775 (4) Å] completes the coordination to form a distorted octahedron. Intermolecular O—H...O hydrogen bonds link the molecules into centrosymmetric dimers, which are further packed by π–π interactions between the 1,10-phenanthroline ligands into layers parallel to the ab plane. The crystal packing also exhibits short intermolecular I...I contacts of 3.6772 (9) Å and weak C—H...O hydrogen bonds.
