The bis-benzimidazolium salts, 1,2-bis[2-(N-R-benzimidazolemethyl)phenoxy] ethane chloride (L1H2: R = Et, L2H2: R = nBu), 1,3-bis[2-(N-R-benzimidazolemethyl)phenoxy]propane chloride (L3H2: R = nPr, L4H 2: R = nBu) and bis[N-R-benzimidazolemethyl]mesitylene 2X (L5H2: R = nBu, X = I; L6H 2: R = PyCH2, X = Br and L7H2: R = PhCH2, X = Br), as well as their eight NHC silver(i), palladium(ii) and mercury(ii) complexes, [(L1Ag)2Ag2Cl 4] (1), [L1(PdCl2CH3CN)2] (2), [(L2Ag)2AgCl2][AgCl2] (3), [(L3Ag2Cl2)n] (4), [(L 4Ag2Cl2)n] (5), [L 5HgI][HgI4]0.5 (6), [L6Hg][HgBr 4] (7) and [L7Ag][(NO3)0.76Br 0.24] (8) have been prepared and characterized. The complexes 1-8 adopt four different structures: (1) with bis-macrometallocycles connected via a Ag2Cl4 unit for 1 and via a AgCl2 unit for 3, (2) an open structure formed via one ligand and two metal atoms for 2, (3) 1D polymeric chains formed by the monomers of a cage-like cavity via weak Ag...Cl bonds (monomer: L3Ag2Cl2 for 4 and L4Ag2Cl2 for 5) and (4) a macrocyclic structure formed by one ligand and one metal for 6-8. In the crystal packing of these complexes, 1D supramolecular chains, 2D supramolecular layers and 3D supramolecular architectures are formed via intermolecular weak interactions, including π-π interactions, hydrogen bonds, C-H...π contacts and weak Hg...Br bonds. Particularly, the catalytic activity of the NHC palladium(ii) complex 2 in Suzuki-Miyaura cross-coupling reactions was studied.
