Abstract
The molecular geometry of silicon tetraiodide was determined by gas-phase e lectron diffraction at 378 K. The molecule has a regular tetrahedral shape with an Si-I bond length (r(g)) of 2.432(5) Angstrom and an I ... I nonbond ed distance (r(g)) of 3.971(8) Angstrom. There is an apparent anharmonicity in both the stretching and the bending vibrations, with the latter especia lly pronounced.
