ResumoCombining BEDO-TTF with 24 kinds of organic acceptors, 19 kinds of metallic complexes were obtained. The first redox potentials of the the acceptors which give the metallic complexes range over 0.82 V that is anomalously big among the organic metals of conventional 1:1 TTF-TCNQ system. The crystal structure of the (BEDO-TTF)5(HCTMM)(Ph-CN)2 salt is regarded as one of the self-aggregated packing motif of the partially charged BEDO-TTF in which the donor interacts to each other through the side-by-side heteroatom network and through the face-to-face stacking. The semiconducting (BEDO-TTF)5(HCP)(Ph-CN)0.2 salt preserves the common structural features to the metallic BEDO-TTF salts. The strong tendency of BEDO-TTF to produce organic metals is attributed both to its low ionization energy and to the ability of its self-aggregation.
