杂多化合物的红外光谱研究
摘要:
本文研究了与Keggin结构相关的31种3大系列(2:18系列,1:11系列和双系列)杂多化合物的红外光谱,它们是:NP2W18(N=(CH3)4N+,(C2H5)4N+,(C4H9)4N+),MP2W18(M=Li+,Na+,Ag+,CU2+);KnZW11(Z=P,B,Ge,Si),MSiW11(M=Mn,Zn,Cu,Co,Ni)和M(PW11)2(M=Ce,Pr,Nd,Sm,Eu,Gd,Tb,Ho,Yb),M(PMo11)2(M=La,Ce,Pr,Sm,Gd,Tb)。总结了各系列杂多化合物氧键的振动规律,讨论了抗衡阳离子对杂多阴离子中氧键的影响,分析了15种相关化合物的纵向联系,证明了1:11系列杂多化合物是八面体弱场配体的论点。

INFRARED SPECTRAL STUDIES OF HETEROPOLY COMPOUNDS
Abstract:
The infrared spectra of three series of thirty-one kinds heteropoly compounds (2:18,1:11 and bis series) related to the Keggin structure e.g. NP2W18(N=(CH3)4N+,(C2H5),N+, (C4H9)4N+), MP2W18 (M=Li+, Na+, Ag+, Cu2+); KnZW11 (Z=P, B, Ge, Si),MSiW11(M=Mn,Zn,Cu,Co,Ni) and M(PW11)2(M=Ce,Pr,Nd,Sm,Eu,Gd,Tb,Ho,Yb),M(PMo11)2(M=La, Ce, Pr, Sm, Gd, Tb) have been compared. The vibrational regularity of oxygen-containing bonds in all heteropoly compounds has been deduced. The effects of countercations on the oxygen bonds of the heteropolyanion were discussed. The verical relationship of compounds related to the fifteen kinds were analysed. The results proved that 1:11 series of heteropoly compounds are octahadral weak-field ligands.
