The reaction of (eta/sup 5/-C/sub 5/H/sub 5/)Re(NO)(CH/sub 3/)(PMe/sub 3/) and PMe/sub 3/ (trimethylphosphine) produced (eta/sup 1/C/sub 5/H/sub 5/)Re(NO)(CH/sub 3/)(PMe/sub 3/)/sub 3/. The reaction is reversible with K/sub eq/ = 0.4 M/sup -2/ at 4/sup 0/C in THF-d/sub 8/. Upon heating at 48/sup 0/C in THF in the presence of high concentrations of PMe/sub 3/, the equilibrium mixture was converted to (Re(NO)(CH/sub 3/)(PMe/sub 3/)/sub 4/)/sup +/(C/sub 5/H/sub 5/)/sup -/, which precipitates from solution. The structure was determined by X-ray crystallography: monoclinic space group P2/sub 1//c, with unit cell constants a = 12.893 (2) A, b = 13.622 (2) A, c = 15.068 (2) A, ..beta.. = 97.47 (2)/sup 0/, and Z = 4. 20 references, 2 figures, 2 tables.
