A new transformable BEDT-TTF complex. (BEDT-TTF)2(IBr2)2(TCE)0.5TCE = 12-Trichloroethanex-A = x-(BEDT-TTF) 2A where x = α or βA = I 3 or IBr 2ε-I 3 = ε-(BEDT-TTF) 2I 3(I 8) 0.5prt. = electrical resistivity at room temperature...
Another BEDT-TTF molecular dimerization is found in α-(BEDT-TTF)2IBr2, which has semiconducting properties and an activation energy that increases with decreasing temperature. These dimerizations are considered to be responsible for the changes in the electrical properties. Superconducting ß-(BEDT-...

Among α-(BEDT-TTF)2MHg(SCN)4 (X = NH4, K, Rb, Tl), the fluctuation of charge order is indicated only in the X = NH4 salt. α′-(BEDT-TTF)2IBr2 shows successive phase transitions to the ferroelectric state keeping a large amplitude of charge order (Δρmax~0.8) over the whole...
It has been found that the types of localization in two compounds under investigation are different: charge carriers in β″-(BEDT-TTF)4NH4[Cr(C2O4)3] are localized on irregular defects of the crystal lattice, whereas charge carriers in α’-(BEDT-TTF)2IBr2 are localized at the regular...
