Four new silver(I) naphthalenedisulphonate complexes, [Ag 2 (1,5-nds) (β-Pic) 4 ]·2H 2 O (1), [Ag 2 (1,5-nds)(γ-Pic) 4 ]·6H 2 O (2), [Ag 2 (2,6-nds) (β-Pic) 4 ] (3) and [Ag 2 (2,6-nds) (γ-Pic) 4 ]·2H 2 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.

Abstract
Four new silver(I) naphthalenedisulphonate complexes, [Ag 2 (1,5-nds) (β-Pic) 4 ]·2H 2 O (1), [Ag 2 (1,5-nds)(γ-Pic) 4 ]·6H 2 O (2), [Ag 2 (2,6-nds) (β-Pic) 4 ] (3) and [Ag 2 (2,6-nds) (γ-Pic) 4 ]·2H 2 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.File | Dimensione | Formato | |
