Abstract

The crystal conductivities of (TTF)2CuCl2 and (TTF)6CuBr4 exhibited metal-like temperature dependence above ca. 200 K. The X-ray analysis of the crystals suggested that the donor molecules form a uniform column without being coordinated to copper, and that the inorganic ions are disordered. The reaction of copper (II) halides with TMTSF and BEDT-TTF yielded (TMTSF)3/2CuCl2 (the powder conductivity was 9 × 10-2 S cm-1 at 300 K), (TMTSF)CuBr2 (7 × 10-4 S cm-1), (BEDT-TTF)2CuCl2 (3 × 10-3 S cm-1), and (BEDT-TTF)7/5CuBr2 (1.7 S cm-1). (TMTSF)CuBr2 was an n-type semiconductor, and others were p-type semiconductors. Magnetic studies showed that the materials can be formulated as (D)n+·CuIX2.
