Synthesis and structures of polymeric silver and mercury complexes with amido-functionalized N-heterocyclic carbenes

Four amido-functionalized N-heterocyclic silver(I) and mercury(II) carbene complexes, [(CH3-imy-CH2CONH2)2Ag2Br2] (3), [Ag(CH3-bimy-CH2CONH2)2]4[Ag4Br8] (4), [Hg(CH3-imy-CH2CONH2)2][HgBr4] (5), and [Hg(CH3-bimy-CH2CONH2)2][HgBr4] (6), have been synthesized and structurally characterized. Crystal packing revealed a 1D polymeric structure of 4 and 2D polymeric structure of 3, 5, and 6.
