A new organic conducting salt, (DMET) 2CuCl 2, was prepared by a diffusion method, crystal and electrical structures of which were investigated. The single-crystal X-ray crystallography revealed that DMET molecules are alternately stacked to form quasi-one-dimensional (Q-1D) columns. This salt exhibited a metallic behavior with lowering temperature ( S cm -1), where several resistance jumps were observed. Key words. Organic conductor - Diffusion method - Crystal structure - Quasi-one-dimensional - (DMET) 2CuCl 2..
