rise to a supramolecular network. Three compounds were investigated for their rich photophysical properties at 298 and 77 K in 2-MeTHF and in the solid state; [Au 2(mu- dmid)(PPh 3) 2] ( 1), [Au 2(mu- dddt)(PPh 3) 2] ( 2), and [AuCl( HOCH 2 CH 2 ) 2 dmit}] ( 4). 1 exhibits relatively long-lived LMCT (ligand-to-metal charge transfer) emissions at 298 K in solution (370 nm; tau e approximately 17 ns
双核金络合物[Au(PPh 3)} 2(mudmid)](1)(dmid = 1,3-二硫代-2-2-1-4,5-二硫代硫酸盐)和[Au(PPh 3)}合成了2(mudddt)](2)(dddt = 5,6-二氢-1,4-二硫氨酸-2,3-二硫代硫酸盐)并通过X射线晶体学进行了表征。两种配合物均表现出分子内亲酸相互作用,Au ... Au距离为1的3.1984(10)A和2的为3.1295(11)A。4,5-双(2-羟乙硫基)-1,3之间的自组装反应-二硫代-2-硫酮((HOCH 2 CH 2)2 dmit)和[AuCl(tht)]得到复合物[AuCl (HOCH 2 CH 2)2 dmit}] 2(4),其具有反平行二聚体排列由于3.078(6)A的短暂亲金接触而产生的。由于经由羟乙基的分子内和分子间氢键,该基序扩展到二维,从而产生了超分子网络。研究了三种化合物在2-MeTHF和固态下在298和77
