Crystal structures and properties of DHTTF salts

The conductivities of (MDHT)(n)X (X=AuCl2, AuBr2 and Au(CN)(2)) were measur ed. These salts have fairly high conductiviites at room temperature and sma ll activation energies. Especially AuBr2 and Au(CN)t salts are conducting e ven at low temperature. The crystal structures of(MDHT)(2)AuCl2 was reporte d. This salt has a columnar structure of donor molecules and largely differ ent crystal parameters from those of AuI2 salt suggesting that AuI2 salt ha s different structure.
