Synthesis and characterization of new silver(I) naphthalenedisulfonate complexes with heterocyclic N-donor ligands: Packing analyses and antibacterial studies. (1st February 2019) - Kumar, Santosh
Graphical abstract: Four new silver(I) naphthalenedisulfonate complexes with heterocyclic N-donor ligands have been synthesized and characterized through spectroscopic techniques and X-ray crystallography. Biological studies indicate they have antibacterial efficacy against both gram positive and gram negative bacterial strains. Abstract: Four new silver(I) naphthalenedisulphonate complexes, [Ag2 (1, 5-nds) ( β-Pic )4 ]·2H2 O (1 ), [Ag2 (1, 5-nds)( γ-Pic )4 ]·6H2 O (2 ), [Ag2 (2, 6-nds) ( β-Pic )4 ] (3 ) and [Ag2 (2, 6-nds) ( γ-Pic )4 ]·2H2 O (4 ) have been synthesized using appropriate starting materials at ambient temperature and normal reaction conditions and fully characterized by spectroscopic methods (FT-IR, NMR). The structures of all the four complexes were determined using single crystal X-ray diffraction techniques and a detailed analysis of the role of weak non-covalent interactions in the solid state (hydrogen bonds, argentophylic interactions, π⋯π interactions) were investigated. Antibacterial activities of all complexes have been evaluated, indicating their high efficacy against both gram positive and gram negative bacterial strains.
