Syntheses, Structures, and Physical Properties of Neutral Gold Dithiolate Complex, [Au(etdt)<sub>2</sub>]·THF

In order to develop new types of single-component molecular conductors with novel electronic structures and physical properties, the neutral gold dithiolate complex with an etdt (= ethylenedithiotetrathiafulvalenedithiolate) ligand, [Au(etdt)<sub>2</sub>] was prepared. However, unlike th...
