We sincerely thank the Irish Research Council (GOIPG/2014/693) and the Science Without Borders Programme (CAPES/BEX/13405-13-6) for financial support.
Reaction of salicylhydroxamic acid (Sha) and 2-aminophenyl hydroxamic acid (2-NH2-pha) with BiCl3 affords the corresponding novel polymeric bismuth chlorido hydroxamato complexes; [BiCl2(-Sha-1H)]∞ and [BiCl3(--Pha-1H)]∞ respectively. The X-ray crystal structure of the THF-solvated polymeric bismuth chlorido salicylhydroxamato complex, [BiCl2(-Sha-1H)(THF)]∞ was solved, confirming the polymeric structure of this class of compounds and the (O,μ-O’)-bidentate bridging coordination mode of the hydroxamato ligand. The antibacterial activity of the THF-free polymeric bismuth chlorido salicylhydroxamato complex, [BiCl2(-Sha-1H)]∞, was investigated against a broad panel of bacteria, further highlighting the antibacterial properties of Bi-based compounds against Gram-positive and Gram-negative pathogenic and environmental strains of bacteria.
