We have succeeded in synthesizing a new Au(III) complex coordinated by a dihydro-TTF-ditiolato ligand, dhdt2- (4,5-dihydrotetrathiafulvalene-4,5-dithiolato) as a tetrabutlylammoium or tetraphenylphosphonium salt. Crystal structural analysis of (Ph4P)[Au(dhdt)2] revealed that the Au(III) ion adopts a square planar coordination and the mean Au-S bond length suggests the Au ions are in the trivalent Au(III) state. A neutral complex, [Au(dhdt)2], was obtained by the electrochemical oxidation of (n-Bu4N) [Au(dhdt)2]. Conducting behavior of [Au(dhdt)2] was semiconductive with conductivity at room temperature of 8.3 Scm-1 and activation energy of 23 meV. Magnetic susceptibility of [Au(dhdt)2] was well explained by the sum of the Curie and temperature independent components.
