摘要：

Reactions of the ethylene- and methylene-bridged bis(imidazolium) salts with an equivalent amount of silver oxide in dichloromethane at room temperature produced readily the silver NHC compounds [Ag2LBr2]. These compounds are partially soluble in DMF. The X-ray structure determination on 3d (L = 1,1'-dibenzyl-3,3'-ethylenediimidazolin-2,2'-diylidene) reveals the formation of bromide bibridged (Ag2LBr2)(n) chains and a unique supramolecular motif with weak (AgAg)-Ag-..., interactions of 3.429 angstrom. Similar to monomeric silver(I) NHC complexes, the silver coordination polymers can also act as carbene transfer reagents for the formation of chelating palladium NHC complexes in excellent yields.
