In the present contribution we report the synthesis and spectroscopic characterization of a new Mn(II) complex with sulfamethoxazole as ligand with formula [Mn(H2O)6]0.5[Mn(SMX)3]. The crystal
structure was determined by single-crystal X-ray diffraction methods. To the best of our knowledge, no previous study on the antibiofilm activity of sulfamethoxazole complex againstS. aureus
