  Photophysical properties, electronic and crystal structures of luminescent diphosphine digold(I)-pyridine-2-thiolate complexes

  摘要：

  Treatment of diphosphine digold(I) complexes, PP(AuCl)(2) [PP-bis(dipheiiylphosphino)methane, dppm; 1,6-bis(diphenylphosphino)hexane, dpph], with two equivalents of pyridine-2-thiol (HNS) in the presence of NaOCH3 affords two luminescent diphosphine digold(I)-pyridine-2-thiolate complexes, dppm(AuSN)(2) (1) and dpph(AuSN)(2) (2), respectively. Both crystal structures have been determined by crystallographic studies. The intramolecular aurophilic contact of 3.0478(3) Angstrom is observed in the crystal structure of I. whereas there is not any aurophilic interaction present in the crystal lattices of 2. At room temperature, I shows a low-energy emission at ca. 660nm 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. (C) 2003 Elsevier B.V. All rights reserved.
