Synthesis and Structure of Dilacunary Decatungstogermanate, [γ-GeW10O36]8-

摘要: The dilacunary decatungstogermanate [γ-GeW10O36]8- (1) has been synthesized and structurally characterized in solution the solid state. Reaction of germanium dioxide with sodium tungstate aqueous acidic medium results formation [β2-GeW11O39]8- (2), which is then used as a precursor for synthesis 1. 183W spectrum 2 shows expected 11 peaks equal intensity, whereas that 1 exhibits three relative intensities 2:2:1. Polyanion represents novel lacunary polyoxometalate, giving rise to multitude derivatives by reaction transition metals, lanthanides, other electrophiles.
