Chemistry of transition-metal vapours. Part I. Reactions with trifluorophosphine and related compounds
Abstract
The known complexes Cr(PF3)6, Fe(PF3)5, Co2(PF3)8, Ni(PF3)4, and Pd(PF3)4 have been formed by condensation of the corresponding metal vapours with trifluorophosphine at –196°. The compound (PF3)3Fe(PF2)2Fe(PF3)3 was also formed in the reaction of iron with trifluorophosphine. Neither manganese nor copper gave volatile products with trifluorophosphine. Condensation of nickel vapour with chlorodifluorophosphine formed Ni(PF2Cl)4 and condensation of nickel vapour with a mixture of phosphine and trifluorophosphine formed the new compounds Ni(PF3)3PH3 and Ni(PF3)2(PH3)2.
