Caesium-templated lanthanoid-containing polyoxotungstates
Abstract
A family of novel lanthanoid-containing polytungstoarsenate(iii) polyanions with interesting structural features has been isolated: six lacunary {alpha-AsW(9)O(33)} building blocks comprising unusual pyramidal WO(5) units are templated by a caesium cation in a central cavity of the structure.
