Crystal Structure of a Silver Sulfaquinoxaline Complex with the Secondary Pyridine Ligand

The crystal structure of a silver sulfaquinoxaline complex with the secondary pyridine ligand Ag2[(C14H11N4O2S)2(C5H5N)2] crystallizes in the orthorhombic P212121 space group with lattice parameters a = 9.8839(15) A, b = 19.228(3) A, c = 19.796(3) A, and α = β = γ = 90°. The secondary ligand in the structure emerges from the solvent pyridine molecule. Each Ag(I) ion is four-coordinated by one Ag(I) ion and two nitrogen atoms from two ligands and one nitrogen atom from pyridine molecules. Furthermore, the antimicrobial activity of the silver sulfaquinoxaline complex and a free ligand is studied by the dilution method.
