Silver(I) And Gold(I) Mono-, Bis- And Tetra-N-Heterocyclic Carbene Complexes: Synthesis, Characterization, Antibacterial And Photophysical Studies

This work describes the synthesis of symmetrical and non-symmetrical benzimidazolium salts as a precursor for the silver(I)-NHC complexes (where NHC = N-heterocyclic carbene). For the first series, seven n-butyl-n’- alkylbenzimidazolium bromide salts (where alkyl = methyl, ethyl, n-propyl, npenty...
