Abstract

Reaction of Na₂WO₄ and NaVO₃ with cis-Ru(dmso)₄Cl₂ in buffer solution (pH 6) led to the formation of a novel polyanion [HVW₇O₂₈Ru(dmso)₃]⁶⁻ (1), which is composed of an unprecedented heptatungstovanadate fragment stabilized by one Ru(dmso)₃ group. The crystallization of 1 with sodium–potassium resulted in Na₄K₂[HVW₇O₂₈Ru(dmso)₃]·Na₃VO₄·15H₂O (1a), which exhibits a 3D architecture formed by the polyanion 1 and sodium–potassium linkers. and sodium–potassium linkers.
