Abstract
Two lattice gas models are proposed for the structural transition near x=4 in LixMo6Se8. These are blocking models: the interactions between intercalated Li atoms are infinite when the atoms occupy certain pairs of sites (so these pairs of sites are never occupied simultaneously), and zero otherwise. The models are solved with an extension of a method proposed by Boureau and Campserveux (1977). This is the first application of lattice gas models to structural distortions in Chevrel compounds.Keywords
