ω-Diazobutanol complexes from the reaction of tetrahydrofuran with bis(dinitrogen) complexes of molybdenum and tungsten: X-ray crystal structure of [MBr{N–NCH(CH2)3OH}(Ph2PCH2PPH2)]+[PF6]–

Abstract

A complex derived from the reaction of tetrahydrofuran with bis-[1,2-bis(diphenylphosphino)ethane]-bis(dinitrogen)tungsten, and previously formulated as a tetrahydropyridazine derivative, has been shown by X-ray structural analysis to be bis-[1,2-bis(diphenyl-phosphino)ethane]bromo-(ω-diazobutanol-N²)tungsten hexafluorophosphate.
