A supramolecular tetra-dawson polyoxothio-metalate: [(α-H2P2W15O56) 4{Mo2O2S 2(H2O)2}4- {Mo4S4O4(OH) 2(H2O)}2]28-

Abstract

Fours for thought: The title compound was prepared by condensation of the preformed unit {Mo2O2S2}2+ as a linker on to the trivacant anion [α-P2W15O5]12-. The self-assembled structure exhibits a modular arrangement (see structure). 31P and 183W NMR spectroscopy revealed that the structure of the supramolecular tetra-unit anion was maintained in solution.
