Organometallic Chemistry of Polyanions(Ⅲ)——Syntheses,Characterization and Properties of Estertin Heteropoly Complexes of PW9O349- with Lacunary Keggin Structure

Abstract

Abstract: Six new heteropoly anion-organometallic complexes M₉ (R'OOCCHR″CH₂SnOH₂)₃·(PW₉O₃₄ )₂]· x H₂O(M=(CH₃)₄N⁺, K⁺; R'=CH₃ _, CH₃CH₂ _; R″=H, CH₃_ ) have been synthesized by reaction of estertin with Na₈HPW₉O₃₄. The products were characterized and their properties were studied by elemental analysis, IR, UV, ¹HNMR, ³¹ P NMR, ¹⁸³W NMRand TGA-DSCmeasurements. The sandwich structure of A, β-PW₉ type for these complexes were determined.

Key words: Heteropoly anion, Estertin, Complexes, Syntheses, Sandwich structure
