Abstract

Hydrothermal synthesis and structural characterization of a new organic polyoxometalate, namely, bis(4,4'-bipyridinium) dodecatungstosilicate dihydrate, 4,4'-bipyH(2)](2)SiW12O40]center dot 2H(2)O (1) is reported. The crystal structure of (1) consists of a SiW12O40](4-) Keggin anion situated on a two-fold axis, two unique 4,4'-bipyridinium cations, one of which is situated on a two-fold axis, and two independent lattice water molecules. The cations and anions are linked by H-bonding.
