Abstract : Synthesis and antibacterial activity studies of four substituted silver(I)-N-Heterocyclic carbene complexes of type [(NHC)2-Ag]Cl2 and their respective (ligands) benzimidazolium salts (6–9) are described herein. The azolium and Ag-NHC analogues were confirmed by H1 and C13-NMR spectroscopy. The synthesized analogues were biologically characterized for in vitro antibacterial activity estimated against some bacteria strains S. aureus. and E. coli.
