AkaiA new charge transfer complex (CPDT-STF)(TCNQ) has been prepared. An X-ray crystal structure analysis revealed that this complex is composed of the donor and acceptor sheets orthogonally arranged to each other, which is similar to (ET)(TCNQ) and (ET)(TCNQF1). The band calculations indicate that the CPDT-STF layer has a significantly two-dimensional interaction, while the TCNQ one has a one-dimensional Fermi surface. The electrical resistivity of the present complex showed metallic temperature dependence down to 0.6K. The thermoelectric power was negative and changed from the positive to the negative gradient at 60K. The static magnetic susceptibility and transport properties indicate coexistence of local and itinerant electrons in the present complex.A. MetalsA. Organic crystalsC.
