Novel cerium(iv) heteropolyoxotungstate containing two types of lacunary Keggin anions†
Abstract
A novel V-shaped polyoxotungstate is formed when CeIV metal centres bridge monolacunary [PW11O39]7− anions to an unusual 1,4-bilacunary [PW10O38]11− anion which appears with an unprecedented bridging structural motif.
