New prepared bis-imidazolium salt that are connected with a 1,2,3-triazol moiety. The Ag(I) and Au(I) complexes [M2(nNHC-NHC)2]PF6. All the prepared ligand and their complexes were confirmed byNMR, FTIR spectroscopy. The biological activity of the formed bis-imidazolium salt and Au(I) and Ag(I) complexes was evaluated against some bacteria strains. The tested compounds showed good activity.
