Neutral Radical Molecular Conductors Based on a Gold Dimethoxybenzenedithiolene Complex with and without Crystal Solvent

Two new neutral radical molecular conductors consisting of a gold dimethoxybenzenedithiolene complex have been successfully synthesized. In these crystals, the p-p stacking manners were significantly altered by the formation of weak hydrogen bonds upon the inclusion of a crystal solvent. Reflecting the structural changes, transport and magnetic properties above transition temperatures were modulated by reduced spin dimerization.
