Studies on the Synthesis and Characterization of Sandwich Type Polyoxometalate （Bu4N）7H3[Ru2O（H2O）2(γ-SiW10 O36)2]
【摘要】 以γ-[Si W10 O3 6]8-及桥联的 K4 Ru2 OCl10 为原料 ,合成了 (Bu4 N) 7H3 [Ru2 O(H2 O) 2 (γ-Si W10 O3 6) 2 ],经红外光谱、电子光谱、顺磁共振、磁化率、循环伏安和核磁共振等的表征 ,证明标题化合物为两聚夹心结构 .其中 ,γ-[Si W10 O3 6]8-结构保持不变 ,填入的 Ru— O— Ru为直线型 ,均保持了原料的基本构型
【Abstract】 A di ruthenium cluster substituted polyoxometalates(Bu 4N) 7H 3[Ru 2O(H 2O) 2( γ SiW 10 O 36 ) 2] was synthesized by using γ [SiW 10 O 36 ] 8- and K 4Ru 2OCl 10 as precursors. Several methods (including IR, UV, EPR, magnetic moment measurement, CV and 183 W NMR) were used to determine the purity and structure of the title compound. IR, UV data confirmed the purity, the maintenance of the γ type structure and the substitution of the di ruthenium cluster; the data of UV, EPR and magnetic moment measurement ensured that the linear structure of K 4Ru 2OCl 10 is still kept; CV and 183 W NMR data determined the C 2h symmetry sandwich structure of the title compound.
