μ-Chlorido-bis-{[1-benzyl-3-(2,4,6-tri-methyl-phen-yl)imidazol-2-yl-idene-κ]silver(I)} chloride 1,2-di-chloro-ethane hemisolvate.

Abstract

A dinuclear silver(I) complex bridged by a chlorido ligand was prepared from an imidazolium chloride precursor bearing benzyl and 2,4,6-trimethylphenyl (mesityl) N-substituents, using sodium bis(trimethylsilyl)amide and silver chloride as reagents. Structural characterization by NMR spectroscopy and single-crystal X-ray diffraction at 110 K revealed monoclinic symmetry (space group 2/m). The crystal packing features multiple weak intermolecular hydrogen-bonding contacts involving the chloride counter-anion. The compound is noted for its potential antibacterial properties.
