Abstract: This brief report outlines the synthesis and analysis of symmetrical dinuclear Ag(I) di-N-heterocyclic carbene (NHC) complexes, primarily derived from tetrakis-benzimidazolium salts. The symmetrical tetrakis-imidazolium salt was synthesized by reacting 1,2,4,5-tetrakis(bromomethyl)benzene with the imidazole moiety of 1‧Br. These salts were then transformed into their respective complexes through an in-situ deprotonation reaction with Ag2O, utilizing different salt-to-metal molar ratios, resulting in the establishment of dinuclear Ag(I) di-NHC complexes designated as Ag1. The structures of both the tetrakis-imidazolium (1‧Br) salts and the Ag(I) di-NHC complex Ag1 were determined using a combination of spectroscopic techniques (FTIR, 1H- and 13C-NMR), CHN elemental analysis, and single crystal X-ray diffraction. The single crystal X-ray diffraction analysis of the macrocyclic complex Ag1 suggests a crystalline structure resembling a cylinder.
