Abstract: The reaction of 5-sulfosalicylic acid (H3-SSA) with o-phenanthroline (Phen), NaOH, and MCl2(M = Zn, Cu) affords Zn (H-SSA)(Phen)(H2O)2(1) and Cu(H-SSA)(Phen)(H 2O)2 (2), respectively. Compounds 1 and 2 are characterized by elemental analysis, IR, fluorescence spectra and single crystal X-ray diffraction analysis. The X-ray diffraction analyses reveal that compounds 1 and 2 are isostructure. The 5-sulfosalicylic acid ligand loses two protons at the sulfo-group and carboxylic group during the reaction. The Zn(II) and Cu(II) ions are six-coordinated and adopt distorted octahedral geometry, which are surrounded by two N atoms from Phen, two O atoms from two water molecules, one O atom from -SO3 group and one oxygen from carboxylic group of the other H-SSA. Compounds 1 and 2 have unprecedented one-dimensional linear chain formed by a repeating mononuclear structural unit, which is bridged by H-SSA. The fluorescence intensity of 1 and 2 is stronger than that of Phen and H3-SSA at 400 nm. The lowest excited single states of these complexes are assigned as mainly Phen localized 1(π,π*). The antibacterial activity test shows that compounds 1 and 2 strongly inhibit the growth of Streptococcus haemolyticus, Straphylococcus aureus and Escherichia coli.
