A novel and large heteropolyanion [(BiW9O33)(3)Bi-6(OH)(3)(H2O)(3)V4O10](12-) has been synthesized by reaction of sodium metavanadate with Na-9[BiW9O33] 16H(2)O in acetate buffer solutions (at pH 4.8). The present anion has a trilobal structure in which three alpha -B (BiW9O33) units are connected to each other by an unique core [Bi,(OH)(3)(H2O)(3)V4O10](15+). A central bismutate/vanadate-mixed core comprises three sets of two types of the BiO6 pentagonal pyramid, the edge-sharing VO5 square-pyramidal triad, and a VO4 tetrahedron.
