The complexes C5H5CuPR3 (R = Me, Pri), C5H5AuPR3 (R = Me, Pri), C5Me5CuPR3 (R = Me, Pri, Ph) and C5Me5AuPR3 (R = Pri, Ph) are prepared from [ClCuPR3]n or ClAuPR3 and LiC5H5 (TlC5H5) or LiC5Me5, respectively. According to the 1H and 13C NMR spectra, the cyclopentadienyl and pentamethylcyclopentadienylgold compounds are fluxional in solution. The X-ray crystal structure of C5H5AuPPr3i has been determined
