摘要: 合成了两个新的银(Ⅰ)配合物,[Ag₂Br₂(DPEphos)₂(dppe)](1)和[Ag(DPEphos)(dppe)]NO₃(2)(DPEphos=双[(2-二苯膦基)苯基]醚;dppe=1,2-双(二苯膦)乙烷),通过红外光谱、X-射线单晶衍射、核磁共振氢谱、磷谱和荧光光谱进行分析和表征。1是由AgBr, DPEphos和dppe以2:2:1的比例混合反应得到的双核化合物,dppe通过2个P原子桥连2个Ag原子,而2是由AgNO₃,DPEphos和dppe以1:1:1的比例混合反应得到的简单的单核化合物,Ag原子与DPEphos和dppe配体螯合。在配合物2的膦谱中,存在4个分裂峰(双峰或者三重峰)。荧光光谱表明所有的发射峰均源于配体中的π-π^*跃迁。

Abstract: Two novel silver(Ⅰ) complexes [Ag₂Br₂(DPEphos)₂(dppe)](1) and [Ag(DPEphos)(dppe)]NO₃(2) (DPEphos=bis[2-(diphenylphosphino)phenyl]ether, dppe=bis(diphenylphosphino)ethane) have been synthesized and characterized by IR, single-crystal X-ray diffraction, ¹H NMR, ³¹P NMR spectroscopy and fluorescence spectra. 1 is comprised of AgBr, DPEphos and dppe in 2:2:1 molar ratio generating a binuclear complex. The dppe ligand bridges two Ag atoms through two P atoms in 1. While, 2 is obtained by the reactions of AgNO₃, DPEphos and dppe in 1:1:1 molar ratio generating a sample mono-nuclear complex. The Ag(Ⅰ) atom is chelated by DPEphos and dppe ligand. In the ³¹P NMR spectra of 2, there are four splitting signals (doublets or triplets). The luminescent spectra show that the origin of these emissions all involves emissive state derived from ligand centered π-π^* transition. CCDC: 1043375, 1; 1043376, 2.
