摘要
Novel polynuclear seven-coordinated potassium complex, [K(bc;b>5b>-Hb>2b>Or)(bc;-Hb>2b>O)]b>nb>(Hb>3b>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 bc;b>5b>-ba;O, O: ba;O′, O′: O″ for Hb>2b>Or−.
