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...

| description | 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 the reported single-component molecular metals, the neutral gold complex [Au(etdt)<sub>2</sub>]·THF (<b>2</b>) contains a solvent molecule of tetrahydrofuran (THF). The crystals of <b>2</b> form a two-dimensional conducting layer structure, which are separated by the terminal ethylene groups and THF molecules. The fairly high room-temperature conductivity of 0.2 S/cm and semiconducting behavior with a low activation energy of 0.1 eV of <b>2</b>, is consistent with the result of the density functional theory band structure calculations. The observed non-magnetic behavior of <b>2</b> is caused from the dimeric structure of [Au(etdt)<sub>2</sub>] molecules. |
