Abstract

In the crystal structure of the title compound, [MoF(N2H2)(C31H29N2P2)(C26H24P2)](BF4)2, each Mo atom is surrounded by four P atoms of one 1,2-bis(diphenylphosphino)ethane and one 2-[bis(diphenylphosphinomethyl)amino]pyridinium ligand. The remaining binding sites of the distorted octahedron are occupied by a hydrazidate (NNH2 2−) and a fluoride ligand. Two F atoms of an anion are disordered over two positions; the site occupancy factors are ca 0.7 and 0.3.
