New Radical Anion Complex, [(CH3)4N][Ni(dmit)2]2 with Metal-Semimetal Phase Transition

Abstract

Abstract The crystal structure determination was made on the multi-sulfur π-acceptor complex, [(CH3)4N][Ni(dmit)2]2, which is the first molecular metal composed of Ni(dmit)2 (dmit=isotrithionedithiolate) molecules and the closed-shell cations. The metal-semimetal transition with large hysteresis was observed.
