The title compound, [Ag2(C2H3O2)2(C19H20N2)2] (2), was readily synthesized by treatment of 3-benzyl-1-(2,4,6-trimethylphenyl)imidazolium chloride with silver acetate. The solution structure of the complex was analyzed by NMR spectroscopy, while the solid-state structure was confirmed by single-crystal X-ray diffraction studies. Compound 2 crystallizes in the triclinic space group P\overline{1}, with a silver-to-carbene bond length (Ag—CNHC) of 2.084 (3) Å. The molecule resides on an inversion center, so that only half of the molecule is crystallographically unique. The planes defined by the two imidazole rings are parallel to each other, but not coplanar [interplanar distance is 0.662 (19) Å]. The dihedral angles between the imidazole ring and the benzyl and mesityl rings are 77.87 (12) and 72.86 (11)°, respectively. The crystal structure features π–π stacking interactions between the benzylic groups of inversion-related (−x + 1, −y + 1, −z + 1) molecules and C—H...π interactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
