Abstract

Abstract : We report on the synthesis and structural characterization of four bismuth(III)‐containing sandwich‐type heteropolytungstates with Bi in 8‐coordination. The three isostructural Keggin‐type ions [Bi(α‐XW11 O39 )2 ] n – {X = Si (1 ), Ge (2 ), n = 13; X = P (3 ), n = 11} and the Wells–Dawson‐type ion [Bi(α2 ‐P2 W17 O61 )2 ] 17– (4 ) were prepared via simple one‐pot synthetic procedures in aqueous medium. The novel polyanions comprise a Bi 3+ ion linking two monolacunary {XW11 } or {X2 W17 } units in a sandwich‐type fashion. The Bi 3+ ion is coordinated by four oxygens of each monolacunary POM unit, resulting in 8‐coordination with square‐antiprismatic geometry. Such a coordination mode is rare for Bi 3+ . Abstract : We demonstrate that bismuth(III) can link two monolacunary Keggin‐ and Dawson‐type heteropolytungstates resulting in sandwich‐type structures with 8‐coordinated bismuth(III) in square‐antiprismatic coordination geometry. The four novel polyanions were characterized in the solid state and in solution.
