| Abstract: | New radical cation salts (TMTSF)23,3′-Co(1,2-C2B9H11)2] (1), (TTF)3,3′-Co(1,2-C2B9H11)2] (2) and (ET)3,3′-Co(1,2-C2B9H11)2] (3) were synthesized and their crystal structures and electrical conductivities were determined. Compound 1 has layered structure with conducting stacks of the TMTSF cations, whereas compounds 2 and 3 contain separated pairs of fulvalenium cations. Conductivity of crystals 1 at room temperature was found to be 15 Ohm−1 cm−1, that is the maximum value found for fulvalenium metallacarborane salts. |
