A new series of radical-cation salts of 2-(4,5-dimethyl-1,3-diselenole-2-ylidene)-5,6-dihydro-4H-cyclopenta-1,3-diselenole has been prepared by electro-oxidation, and the temperature dependence of the d.c. electrical conductivities of the salts is reported; very high conductivities are observed with no sign of either a metal–insulator or a superconducting phase transition even at very low temperature (0.1 K).
