μ-Chlorido-bis{[1-benzyl-3-(2,4,6-trimethylphenyl)imidazol-2-ylidene-κC]silver(I)} chloride 1,2-dichloroethane hemisolvate

The title compound, [Ag 2 (C 19 H 20 N 2 ) 4 ]Cl·0.5C 2 H 4 Cl 2 , can be readily generated by treatment of (1-benzyl-3-(2,4,6-trimethylphenyl)imidazolium chloride with sodium bis(trimethylsilyl)amide followed by silver chloride. The molecular structure of the compound was confirmed using NMR spectroscopy and single-crystal X-ray diffraction analysis. The crystal structure of the title compound at 110 K has monoclinic ( P 2 1 / c ) symmetry. The represented silver compound is of interest with respect to antibacterial properties and the structure displays a series of weak intermolecular hydrogen-bonding interactions with the chloride counter-anion.
