Molybdenum complexes have been known to catalyze the generation of H2 from water as well as the formation of ammonia from dinitrogen. In this project, the coordination chemistry of molybdenum complexes supported by a diphosphine p-terphenyl ligand is explored. Different molybdenum-arene binding modes were observed depending on metal oxidation state. A molybdenum(II)-acetonitrile species has been utilized as a precursor for the generation of species displaying molybdenum-element multiple bonds. Reactions with azides and hydrides will be discussed. The prepared complexes were characterized by a variety of techniques and their reactivity was investigated.
