In the current study, 1-butyl-3-propylbenzimidazolium bromide salt (1) was used as a carbene precursor to facilitate the formation of complex [NHC–Ag(I)–NHC]PF₆ (2) (NHC = N-heterocyclic carbene) via in-situ deprotonation method with Ag₂O. Furthermore, the formation of complex [NHC–Au(I)–NHC]PF₆ (3) was achieved through a transmetalation approach of 2 with Au(SMe₂)Cl. The formation of all compounds was proved by elemental analyses, FTIR, ¹H- and ¹³C NMR. The successful complexation of NHC ligand with Ag(I) and Au(I) ions were suggested by the disappearance of H2′ carbene proton peak which previously present in the spectrum of 1 at 9.784 ppm. In addition, the shift of C2’ carbene carbon peak from 142 ppm in the spectrum of 1 to the area of 187–190 ppm in the spectra of 2 and 3 supports the formation of these metal-NHC complexes. Crystal analysis of 3 shows that the complex consists of one Au(I) ion in a linear geometry that coordinates to two NHC ligands with the presence of one PF₆⁻ cation in the lattice stabilizes the entire structure. In solid-state photophysical study of 3, upon excitation at 340 nm, complex 3 displays an intense photoluminescence with a strong emission maxima, λ_em = 500 nm at room temperature.

在当前的研究中，使用1-丁基-3-丙基苯并咪唑溴化盐（1）作为卡宾前体，以促进络合物[NHC–Ag（I）–NHC] PF ₆（2）（NHC = N-杂环碳烯通过Ag ₂ O的原位去质子化方法。此外，通过2与Au（SMe ₂）Cl的重金属化方法实现了络合物[NHC–Au（I）–NHC] PF ₆（3）的形成。所有化合物的形成均通过元素分析，FTIR，¹ H-和¹³证明1 H NMR。NHC成功络合有Ag（I）和Au配体（I）离子通过的消失表明H2'卡宾质子峰这在以前存在于光谱1 在9.784 ppm的。此外，C2'卡宾碳峰从1光谱中的142 ppm到2和3光谱中的187-190 ppm区域的移动支持了这些金属-NHC络合物的形成。的晶体分析3示出了复合物由一个金（I）离子的线性几何形状的坐标两个NHC与一个的存在PF配体₆ ^-晶格中的阳离子稳定了整个结构。在固态光物理研究3在340nm处，激发时，复杂的3个显示强烈的光致发光具有较强的发射最大值，λ _EM  =在室温下为500nm。
