Abstract
Abstract The reaction of (acetonitrile)-undeca(carbonyl)-tri-osmium(0) and bis( tert -butyl)fluorophosphine led to the formation of (bis( tert -butyl)fluorophosphine) undeca(carbonyl)-tri-osmium(0) ( 1 ). However, the reaction of bis(acetonitrile)-deca(carbonyl)-tri-osmium(0) and bis( tert -butyl)fluorophosphine yielded bis(bis( tert -butyl)fluorophosphine)-deca(carbonyl)- tri -osmium(0) ( 2 ) and ( tert -butyl-difluorophosphine)(bis( tert -butyl)fluorophosphine)-deca(carbonyl)-tri-osmium(0) ( 3 ). Compounds 1 and 2 are the first aliphatic mono-fluorophosphine osmium clusters and were characterized by an X-ray diffraction study. Both compounds show a regular three-membered osmium cycle with equatorially oriented phosphorous atoms. Compound is 3 is the first example of a mixed mono-fluorophosphine-difluorophosphine compound and has been characterized by NMR spectra, a mass spectrum and an IR spectrum.
