The instable trifluoromethylstannanes (CF3)nSnH4−n (n = 1–3) have been obtained from the corresponding halides by reaction with Bu3SnH at −40°C. Their physical properties have been determined, and their vibrational spectra have been analyzed. The 1H, 19F, 13C and 119Sn NMR spectra have been recorded; trends in coupling constants are interpreted based on 5s(Sn) orbital contributions. For the analogous
