technique to obtain a mononuclear Ag(I)-NHC complexes (3 and 4). The mononuclear Pd(II)-NHC complexes (5 and 6) were prepared via transmetalation from their respective Ag(I)-NHC complexes, respectively. All compounds were characterized by elemental analyses, FT-IR, 1H- and 13C-NMR. Single crystal structural studies of Ag(I)-NHC complex revealed that the Ag(I) ion exhibits a linear geometry of quasi-parallel

A new series of N‐heterocycliccarbene (NHC) ligand precursors (1 and 2) with their [Ag(I)(NHC)2]PF6 complexes (3 and 4) and [ClAu(I)(NHC)] complexes (5 and 6) are reported. Complexes 5 and 6 were synthesized via transmetalation reaction using either 3 or 4 and AuCl(SMe2) as reactants, respectively. All the synthesized compounds were fully characterized using elemental analyses and Fourier transform
一系列新的N杂环卡宾(NHC)配体前体(1和2)及其[Ag(I)(NHC)2 ] PF 6配合物(3和4)和[ClAu(I)(NHC)]配合物(5和6)。配合物5和6通过过金属化反应分别使用3或4和AuCl(SMe 2)作为反应物合成。使用元素分析和傅里叶变换红外光谱,1 H NMR和13对所有合成的化合物进行了充分表征13 C NMR光谱学。在的晶体结构3,5和6,所述的Ag(I)和Au(I)离子是线性几何形状。3的整个结构通过显着的π-π相互作用而稳定,而5和6的结构通过相邻的Au(I)离子之间的嗜酸相互作用以及CH-π或π-π相互作用而得以稳定。根据光致发光研究,配合物5和6具有双重发射特性。高能量的荧光源于1 XLCT和1 MLCT的混合,而低能量的磷光归因于3XLCT和3 MLCT对3 ILCT的贡献很小,这由密度泛函理论(DFT)和建模分子的时间依赖DFT计算证明。
