Abstract
The bis(ethylenedithio) tetrathiafulvalene salt (BEDT-TTF)3Cl2·2H2O (1) has been prepared and characterised by single crystal X-ray diffraction, four probe electrical conductivity, and e.s.r. measurements, showing a metallic 2D network of BEDT-TTF molecules, separated by complex anions consisting of units of 4Cl– and 4 H2O molecules (σ= 0.6 S cm–1 at 300 K) with a metal–insulator transition at 100 K; activated behaviour of the spin susceptibility in the metallic regime is tentatively ascribed to Peierls fluctuations, lowering N(εF) with temperature.Keywords
