The molecular structure of triiodomethane (iodoform, CHI3) has been determined by gas electron diffraction. The structural parameters (r g/Å and ∠α/°) with the estimated limits of error (3σ) are: r(C-H) = 1.111 (assumed), r(C-I) = 2.145(8), r(I...I) = 3.549(2), ∠ICI = 111.9(7), ∠ICH = 107.0(7). Mean amplitudes, l(C-I) and l(I⋯I), have also been determined. The C-I distance of CHI3 is equal to that of CI4 within experimental uncertainties.
