Abstract: Intercalate materials, which exhibit retrograde solubility without variation in the aggregate state, are of interest for the formation of nanostructured composites, since they make it possible to perform the decomposition at a relatively low temperature and to obtain stable nanoinclusions. In order to broaden the range of such materials, a new Cu–TiTe$_2$ intercalate system is synthesized. The crystal structure and the temperature dependence of solubility of copper are investigated. It is shown that the enhancement of the covalent component of the intercalant-lattice chemical bond as compared to the Cu$_x$TiSe$_2$ system leads to the retrograde solubility character.
