The molecular structure and vibrational characteristics of monomeric and dimeric tin diiodide, SnI2 and Sn2I4, were determined by high-level computational methods. For the dimer molecule two low-energy geometries were found, one with C s and the other with C 2v symmetry, the former with somewhat lower energy; their relative energy is strongly dependent on the computational method. Thermodynamic functions for both species and their dimerization reaction were calculated based on the computed structures.
