Silver compounds, free or weakly bound silver ions as well as silver nanoparticles have all been shown to be good antibacterial agents. On the other hand there have been comparatively very few studies into the antifungal properties of silver complexes , most of which focus on the use of silver nanoparticles. Compounds Ag1 and Ag2 are interesting as they show exclusive antifungal activity, with no inhibition of bacterial growth observed in our assays. This is in contrast to free (weakly bound) silver ions e.g. AgNO3, which effectively inhibit both bacteria and fungi but also cause some degree of haemolysis in our assays (Table in SI). The ligands for these complexes (Ligand-Ag1 and Ligand-Ag2 in the SI) were originally studied for their solvatochromism and were later coordinated with silver to investigate their potential antimicrobial activity. The carboxylate ion is able to coordinate to silver with monodentate, chelating, and/or bridging modes. Since the difference in frequencies (Δv) between symmetric and asymmetric vibrations of the -COO group in FT-IR peaks is well under 200 cm -1 the bridging mode is suggested. To understand the solution behaviour of these complexes, the stability of complexes Ag1 Similarly, no significant changes could be detected in the UV-vis spectra (DMSO) after 24 hours (20 μM) (Figure in SI).
