The molecular structure of trimethylamine–boron triiodide (CH3)3N·BI3 has been determined from gas electron-diffraction data. The molecular parameter values and their uncertainties are rg(B–I)=2.245±0.004 A, rg(N–B)=1.663±0.013 A, rg(C–N)=1.497±0.005 A, rg(C–H)=1.103±0.010 A, ∠IBI=108.6±0.4°, and ∠CNC=106.0±0.8°. The potential barrier around the N–B bond has also been estimated to be about 3.5 kcal
