title: A novel hexatungstate fragment stabilized by dimethyltin groups: [{(CH3)2Sn}2(W6O22)]4-.
abstract: Reaction of Na2WO4 and (CH3)2SnCl2 in water (pH 7) led to the formation of the hybrid organic-inorganic polyanion [{(CH3)2Sn}2(W6O22)]4- (1), which is composed of a novel hexatungstate core stabilized by two dimethyltin groups. Selective crystallization of 1 with guanidinium cations resulted in [C(NH2)3]4[{CH3)2Sn}2(W6O22)]2H2O (1a), which exhibits a 1D arrangement via distorted trigonal-bipyramidal cis-(CH3)2SnO3 moieties.
