Abstract Crystals of compounds occurring in the solid solution range CsSnBr3-CsSnCl3 have been prepared by pulling from the melt and by Bridgman growth. The materials show a consistent change in colour and electrical resistivity from the black metallic conductor CsSnBr3 to the bright yellow CsSnCl3. The as-grown compounds undergo various structure changes from the cubic, high temperature form to lower symmetry forms on standing. These changes have been followed by DTA; they are also apparent as colour changes. X-ray examination indicates that the compounds react with atmospheric moisture to form monohydrates. The products showed some differences in their structural stability from powders of the same composition precipitated from solution. These differences are attributed to particle size effects analogous to those encountered in ferroelectric perovskites.
