ResumoThe preparation, crystal structure and physical properties of normal spinel Cu1−xTi2S4 are reported. A large range of compositions (0⩽x⩽0.44) has been observed. Single crystals have been obtained by chemical vapor transport reaction with iodine or chlorine pressure. The refinement of the structure (67 reflexions) corroborates the previous normal spinel structure and indicates for this crystal a composition of Cu0.93Ti2S4. Electrical and magnetic properties have been measured for some single crystals. They are consistent with the metallic conductivity as shown by the proposed band structure model.
