Silver(I) complexes based on cyclic arsine ligands: Synthesis, structure and bioactivity

Silver(I) complexes containing cyclic arsine ligands, namely 10-arylphenoxarsines L1 - L4 and 10-phenyl-5,10dihydrophenarsazine L5, have been synthesized by the reactions of AgBF4 with the cyclic arsine ligands in different molar ratios. All complexes are characterized by 1H NMR, mass-spectrometry, elemental analysis, and X-ray diffraction. All complexes exhibit moderate to enhanced antimicrobial activity against both Gram-positive and Gram-negative bacteria, fungi as well as anticancer activity against M-HeLa and HuTu 80 cell lines.
