The activation and functionalisation of the exceptionally strong C F bond is a challenging goal for organometallic chemists. Moreover, the study of bond energies of metal fluorides with hydrogen or halogen bonds is of increasing interest for e. g. coordination and organometallic chemistry, supramolecular chemistry and crystal engineering or molecular recognition. Metal halide complexes have shown to be suitable for the investigation of such interactions, being a good acceptor for hydrogen bonds and halogen bonds. The synthesis of an isostructural series of such complexes of one transition metal group has not been done before, except for group 4. For comparing the strength of different metal-fluorine bonds systematically, a number of complexes of group 8 and group 10 metals will be synthesised, utilising N-heterocyclic carbenes and bulky phosphines as ligands. The interactions of these compounds with organic donors will then be investigated by multinuclear NMR spectroscopy.

对于有机金属化学家来说，极强的碳氟键的活化和官能化是一个具有挑战性的目标。此外，金属氟化物与氢键或卤键的键能的研究在配位和有机金属化学、超分子化学和晶体工程或分子识别等方面也越来越引起人们的兴趣。金属卤化物络合物是氢键和卤键的良好受体，适合于研究这种相互作用。为了系统地比较不同金属-氟键的强度，以N-杂环卡宾和大分子膦为配体，合成了一些第8族和第10族金属的配合物。然后用多核核磁共振波谱研究这些化合物与有机给体的相互作用。
