| Abstract: | The metal-semiconductor (or metal-metal) transitions of two isomorphous BEDT-TTF (ET) compleses, (ET)2ClO4X0.5 With an asymmetric X = C2H3Cl3 and a symmetric C2H4Cl2 molecule are investigated. The order-disorder configuration changes of the ethylene groups in ET molecules, in addition to the disorder introduced by the asymmetric structure of the molecule for the former complexes, play an important roles in determining the nature of the transitions. |
