We describe the synthesis of a series of molybdenum (Mo) complexes supported by a para-terphenyl diphosphine (P2) ligand, displaying metal-arene interactions. Treatment of P2 with Mo tricarbonyl precursors yields the Mo0 species, P2Mo(CO)3. Two electron oxidation followed by photolytic decarbonylation gives a MoII complex, [P2Mo(MeCN)2]2+. Sodium azide oxidizes this species to yield a MoIV nitride-azide complex. Reduction with magnesium furnishes a Mo0 dinitrogen complex, P2Mo(N2). This dinitrogen species reacts cleanly with CO2, H2, or PhSiH3 providing a �2-CO2 complex, a Mo dihydride, and a phenyl silyl hydride species, respectively. The structure, characterization, and further reactivity of these P2 Mo complexes will be discussed.
