摘要：

Five members of the family Zn//mIn//2S//3// plus //m are studied by means of electron microscopy. It is found that all the compounds present hexagonal structures, with the same a-lattice parameter. The c-lattice constant depends on the stoichiometry, following a certain formula. In all the examined materials, composition faults are found, mainly as isolated faults and with an m-value smaller than the bulk material. Several polytypic forms, corresponding to the same composition, also exist. ZnS-rich crystals present no superstructure, most probably because of a random distribution of the cations in their sublattice.
