Abstract
The molecular structure of trimethylphosphine–boron tribromide (CH3)3P·BBr3 has been determined from gas electron-diffraction and vibrational-spectroscopic data. The molecular parameters and their uncertainties were rg(B–Br)=2.010±0.009 A, rg(P–B)=1.946±0.029 A, rg(C–P)=1.804±0.004 A, rg(C–H)=1.098±0.010 A, ∠BrBBr=111.7±0.7°, and ∠CPC=108.0±0.7°. The potential barrier around the P–B bond was also estimated to be about 10 kcal mol−1 (1 cal=4.184 J).
