Abstract
Reaction of N, N′-dimethylimidazolium iodide with Ag 2O in CH 2Cl 2 leads to the coordination polymer [Ag(carbene) 2] 2[Ag 4I 6] ( 2), which consists of the cation [Ag(carbene) 2] + and anionic infinite one-dimensional [Ag 4I 6] 2− chain. The cations and anionic chains are connected into two-dimensional network structure. Treatment of N-allyl- N′-methylimidazolium iodide with Ag 2O yielded a tetranuclear N-heterocyclic carbene silver complex [Ag(carbene) 2] 2[Ag 2I 4] ( 3). The polymeric [Ag(carbene)][AgI 2] ( 4) was isolated when the tetranuclear complex 3 was heated at 80 °C. The monocarbene complex 4 adopts infinite one-dimensional ribbon stair structure in which the silver atoms are held together by multiple iodide bridges and weak Ag⋯Ag interaction. The compounds have been fully characterized by elemental analysis, NMR spectroscopy, and X-ray crystallography.
