Novel trinuclear rhodium-hydride complexes with diphosphine ligands Tangphos, t-Bu-BisP*, and Me-DuPHOS which contain bridging μ(2)- and μ(3)-hydrides as well as terminal hydrides in one molecule have been reported recently. In this work, these different rhodium-hydride bonds are characterized by Raman spectroscopy and the results are compared with those obtained by means of the more commonly applied IR spectroscopy. Density functional theory (DFT) calculations have been carried out to support the experimental findings. The structure of the Rh(3)H(7) core is described in the context of their vibrational stretching modes.
最近报道了含有桥联 μ(2)-和 μ(3)-氢化物以及一个分子中末端氢化物的新型三核铑-氢化物配合物,该配合物具有二膦配体 Tangphos、t-Bu-BisP* 和 Me-DuPHOS。在这项工作中,通过拉曼光谱对这些不同的铑-氢键进行了表征,并将结果与更常用的红外光谱法获得的结果进行了比较。通过密度泛函理论(DFT)计算来支持实验发现。在讨论它们的振动伸缩模式时,描述了 Rh(3)H(7)核的结构。
