Investigation of novel oxyfluoride compounds of the late transition metals by matrix-isolation spectroscopy

该项目旨在研究迄今未知的后过渡金属氧氟化物。早期过渡金属氧氟化物中的Sc-Te-Fe基团是众所周知的。然而，到目前为止，对于Co-Tl-Cu-基团来说，氧氟化物的物种是未知的。到目前为止，唯一没有任何疑问的后过渡金属氧氟化物物种是OHgF，它被基质隔离光谱所表征。在这个研究项目中，我们想要研究这一未知的陆地，以扩展我们对过渡金属氟氧化物的了解。所讨论的化合物将通过基质隔离光谱进行表征，该光谱提供了各种实验光谱工具，并将得到最先进的量子化学计算的补充。除此之外，化学键的性质特别令人感兴趣，正如我们对OHgF物种所显示的那样。这就是为什么我们的目标是研究新型的含氧氟化合物--铱、铂和金。特别是基质隔离光谱是研究的首选方法，因为在这样的低温条件下，可以防止双分子反应，甚至可以稳定脆弱的化合物。

The project aims at the investigation of so far unknown oxyfluorides of the late transition metals. Early transition metal oxyfluorides are well known for the Sc- till Fe-groups. However oxyfluoride species are so far unknown for the Co- till Cu-groups. So far the only oxyfluoride species without any doubt of the late transition metal is the OHgF which was characterized by matrix-isolation spectroscopy. In this research project we like to investigate this terra incognita to extend our knowledge of transition metal oxyfluoride compounds. The compounds in question will be characterized by matrix-isolation spectroscopy, which offers a variety of experimental spectroscopic tools and will be complemented by state-of-the-art quantum-chemical calculations. Beyond this the nature of the chemical bonding situation is of special interest as it was shown by us for the OHgF species. That is why we aim in the investigation of novel oxyfluoride compounds of iridium, platinum and gold. Especially the matrix-isolation spectroscopy is the method of choice for such investigations as bimolecular reactions can be prevented and even fragile compounds can be stabilized under such cryogenic conditions.
