The Novel Polymeric Potassium Complex with a New Coordination Mode of Orotic Acid [K(μ5-H2Or)(μ-H2O)]n : Synthesis and Structural Characterization

Abstract

Novel polynuclear seven-coordinated potassium complex, [K(μ<inf>5</inf>-H<inf>2</inf>Or)(μ-H<inf>2</inf>O)]<inf>n</inf>(H<inf>3</inf>Or = orotic acid), with the new coordination mode of orotic acid has been prepared and characterized by elemental analysis, FT-IR spectra, X-ray diffraction. The orotate ligand exhibits new coordination mode of μ<inf>5</inf>-κO, O: κO′, O′: O″ for H<inf>2</inf>Or-. © 2007 Elsevier B.V. All rights reserved.
