Synthesis and characterization of [Acridinium][Ni(dmit)2]3, a new metallic conductor

[Acridinium][Ni(dmit)2]3 has been synthesized by electro-oxidation of [acridinium][Ni(dmit)2]. The compound has been characterized by X-ray crystallography, conductivity measurements and intermolecular orbital overlap integral calculations. The compound shows a metallic conductivity behavior down to 4 K, which was confirmed by the overlap integrals.
