Özet

The title compound, [Ag2Br2(C46H50N4)], contains a bulky bis(N-heterocyclic carbene) ligand, comprising two benzimidazolium groups linked through a 2,3,5,6-tetramethyl-1,4-xylylene bridge. The compound was formed by reaction of the bromide salt of the ligand with Ag2O in dichloromethane. The discrete compound is formed in preference to a postulated coordination polymer. Each Ag-I atom is coordinated by the carbene C atom and two Br atoms in a trigonal planar geometry.
