Abstract

A cage-like {[Ca(H₂O)]₆(H₂O)}¹²⁺ cluster with a water molecule enwrapped, sandwiched by two novel [As₄W₆O₃₄]¹²⁻ fragments, has been obtained, and the extension of these clusters from molecules into a 2-D layer occurs through [Ca(H₂O)₅]²⁺ linkers, which represents the first heteropolyoxoanion (HPA) constituted by [As₄W₆O₃₄]¹²⁻ and the unprecedented high nuclearity {[Ca(H₂O)]₆(H₂O)}¹²⁺ cluster.
