| 摘 要： | 研究了簇合物Et4N]2Mo2（CO)8（μ-SPh）2]（1）、MO2（CO）8（μ-SPh）2（2）、MO2－（CO）6（μ-SPh）2（CH3CN）2（3）、Mo2（CO）6（μ-SPh）2（PPh3）2（4）的红外和共振Raman光谱。分别对它们的特征振动频率进行了归属。研究了Mo2（CO）6（μ-SPh）2L2中L的σ给体强度和π受体强度对影响的协同效应。结果表明，在3中CH3CN的π受体强度和4中PPh3的σ给体强度对的影响起主导作用。在2、3、4中L的σ效应对的影响起主导作用。

| Abstract: | The IR and Resonance Raman Spectra of cluster compounds have been investigated and their characteristic vibration frequencies were assigned. The synergism between the influences of π acceptor and σ donor abilities of ligands L on have been studied. The results indicate that the π acceptor ability of CH3CN in 3 and σ donor ability of PPh3 in 4 play the leading role which influence the are influenced mainly by the σ effect of the L ligands. |
