Synthesis, Crystal Structure, Spectroscopic and Thermal Properties of a Novel Complex of Hydantoin-5 Acid With Co(II)

Abstract

The complex, tetraaqua bis(hydantoin-5-acetato) cobalt(II) was synthesized by the reaction of hydantoin-5-acetic acid and CoCl<inf>2</inf>·6H<inf>2</inf>O presence of NaHCO<inf>3</inf>. The structure of the complex was determined by X-Ray single crystal data the thermal analyses, FT-IR and magnetic susceptibility data are also presented. The monoclinic crystal of the title compound, [Co(C<inf>5</inf>H<inf>5</inf>N<inf>2</inf>O<inf>4</inf>)<inf>2</inf>(H<inf>2</inf>O)<inf>4</inf>], lie across centers of inversion in space group P21/c. The complex features a distorted octahedral [CoO<inf>6</inf>] coordination with hydantoin-5-acetato and water ligands. The hydantoin-5-acetato anion is bonded to the cobalt(II) ion via its deprotonated carboxylic acid O atom. The complex molecules show three dimensional supramolecular networks by O-H···O and N-H···O interactions. © 2013 Springer Science+Business Media New York.
