Photoelectronspectra have been recorded for [M(CO)3(η6-C3But3P3)] (M = Cr, Mo or W) and [Mo(CO)3(η6-C3But3H3)]. They are assigned by comparison with analogous spectra and density functional calculations. The phospha-arene complexes show a higher first IE than carbocyclic analogues. Electronicstructure analysis indicates stronger bonding in the former as a result of greater metal–ligand back donation
光电子能谱已被记录为[M(CO)3(η 6 -C 3卜吨3 P 3)](M =的Cr,MO或W)和[沫(CO)3(η 6 -C 3卜吨3 H 3)]。通过与类似光谱和密度函数计算的比较来分配它们。膦-芳烃配合物显示出比碳环类似物更高的第一IE。电子结构分析表明,由于向P取代的环的较低的LUMO分子提供了更多的金属配体,因此前者的键合更牢固。
