Popis:	(Cu6PS5I)1–x(Cu7PS6)x mixed crystals were grown using the direct crystallization technique from melt (Bridgman–Stockbarger technique). The polymer composites based on (Cu6PS5I)1–x(Cu7PS6)x mixed crystals were prepared. Electrical properties of composites were studied in the frequency range from 10–3 Hz to 2·106 Hz at room temperature. The parallel equivalent circuit with double electric layer assumed at the electrode interface was applied to analyze the frequency dependences of electrical conductivity. It has been shown that the highest value of total electric conductivity is observed for the (Cu6PS5I)0.75(Cu7PS6)0.25-based composite. The further increase of Cu7PS6 content leads to the monotonically decreasing values of total electric conductivity. The ratio of total ionic to electronic components demonstrates the highest value for Cu6PS5I-based composite.
