金属簇合物具有独特的结构和成键方式。本文对铑簇合物的简正振动分析进行了研究。通过红外光谱用石蜡油糊涂KBr和聚乙烯窗口, 在Nicolet 200SXV FT-IR光谱上测定了Rh2(CO)4(μ-Cl)2的构型, 并使用分子振动全分析程序MVTA(Basic语言), 在PC机上进行计算。

Force constants of Rh2(CO)4(m-Cl)2 and Rh(m-CO)3(CO)9 were obtained on the basis of general valence force field computation. The calculated frequencies are in good agreement with the observed spectra. The strength of M-M and M-L bonds, the effects of bridging ligands on M-M stretching, and the various approx. force fields for clusters are discussed.
