Both crystal structures have been determined by crystallographic studies. The intramolecular aurophilic contact of 3.0478(3) is observed in the crystal structure of 1, whereas there is not any aurophilic interaction present in the crystal lattices of 2. At room temperature, 1 shows a lowenergy emission at ca. 660 nm as well as a very weak high-energy emission at ca. 496 nm in the solid state, but 2 shows only a strong high-energy one at ca. 482 nm. Thus, the emission energy strongly dependent on the Au(I) Au(I) interaction can be demonstrated in the diphosphine digold(I) thiolates studied herein. |
