Abstract

A new radical cation salt based on the dithiolate complex Pd(dddt)2 (dddt=5,6-dihydro-1,4-dithiine-2,3-dithiolate) with the tetrahedral anion [GaBr4] was synthesized. The crystal and molecular structure was determined by XRD analysis. The crystal structure of the salt contains Pd(dddt)2 cation layers alternating with layers of [GaBr4] anions along thec axis of the unit cell. The cation layers contain stacks of Pd(dddt)2, with a Pd...Pd distance of 3.011 Å. The electroconductivity of [Pd(dddt)2]2GaBr4, single crystals at room temperature is 0.25 Ohm−1 cm−1 and decreases with temperature decrease, the activation energy beingE a=0.66 eV.
