新型电荷转移配合物(C_9H_8N)_10(NH_4)_3[Y(SiMo_(11)O_(39))_2]·20H_2O的合成与表征

Synthesis and Characterization of (C_9H_8N)_10(NH_4)_3[Y(SiMo_(11)O_(39))_2]·20H_2O Charge-Transfer Complex

由三元杂多化合物 (NH4) 1 3 [Y(Si Mo1 1 O3 9) 2 ]· 36 H2 O与喹啉反应合成了电荷转移化合物 (C9H8N) 1 0(NH4) 3 [Y(Si Mo1 1 O3 9) 2 ]· 2 0 H2 O。采用元素分析、X射线粉末衍射、红外光谱、固体漫反射电子光谱进行了表征。结果表明 :喹啉通过 N原子结合质子形成阳离子与稀土杂多阴离子成盐 ,固体化合物中阴离子和阳离子之间存在较强的相互作用 ;化合物在光激发下发生分子内电荷转移 ,导致有机 C9H8N+大阳离子的氧化和稀土杂多阴离子的还原 。

The charge-transfer salt between quinoline and Y Si Mo tribasic polyoxometalate with Keggin stucture has been synthesized Its structure and properties were investigated by elemental analysis ,ICP, IR, UV-vis,XRD, and TG Spectroscopic data support the presence of an electronic interaction between electron-rich aromatic organic and inorganic anions in the solid state.
