Abstract

Mixed ligand complexes of Ag(I) with triphenylphosphine (PPh3), triphenylphosphine sulfide (SPPh3), triphenylphosphine selenide (SePPh3) and Imidazolidine-2-thione (Imt) have been prepared. The solution as well as solid state NMR studies have been carried out to characterize these complexes. Both solid and solution NMR show the coordination via thione group on one side and (S/Se) or PPh3on the other side. A higher antimicrobial activity is shown by [ImtAgPPh3]Cl complex against gram negativePseudomonas aeruginosa(P. aeruginosa) andEscherichia coli(E. coli) compared to the other two complexes i.e. [ImtAgSPPh3]Cl and [ImtAgSePPh3]Cl.
