摘要：

A new bis(ethylenedithio)tetrathiafulvalene complex with copper bromide, [BEDT-TTF]8[Cu(II)Br4]Br3, was obtained by a direct redox reaction between BEDT-TTF and [Cu(II)Br4]2-. The compound crystallizes in the space group Pccn with a = 34.062(6), b = 8.498(1) and c = 11.427(2) angstrom. The two different kinds of anions are statistically distributed at crystallographically equivalent sites. Close side-by-side contacts of adjacent donor molecules form a one-dimensional array; the shortest S-S distance is 3.343 angstrom. The one-dimensional chains are linked by face-to-face stacks: the shortest S-S distance in the stacks is 3.520 angstrom. The ESR spectrum shows a broad copper(II) signal: g = 2.08-2.17 and peak-to-peak width = 120-175 G, depending on the crystal orientation with respect to the magnetic field.
