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

该项目的目的是研究迄今为止未知的晚期过渡金属的氟氧化物。早期的过渡金属氟氧化物以Sc到fe基团著称。然而，Co-和cu -基团的氟化氧种类至今未知。到目前为止，唯一可以确定为晚期过渡金属的氟氧化合物是OHgF，并通过基质分离光谱对其进行了表征。在这个研究项目中，我们希望调查这一未知领域，以扩展我们对过渡金属氟化氧化合物的认识。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，并将辅以最先进的量子化学计算。除此之外，化学键情况的性质是我们特别感兴趣的，因为它是由我们展示的OHgF物种。这就是为什么我们致力于研究铱、铂和金的新型氟化氧化合物。特别是在这种低温条件下，可以防止双分子反应，甚至可以稳定脆弱的化合物，因此基质分离光谱是研究的首选方法。

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.
