The title compound (1a) and its related unsymmetrical derivatives were prepared as new donors for organic conductors, and electrochemical properties and crystal structure of 1a were investigated. Several charge-transfer complexes and cation radical salts using them showed metallic temperature dependence of conductivity down to ca. 100 K.
