ABSTRACT

A nickel complex of 4-amino-N-(2-pyrimidinyl)benzenesulfonamide (sulfadiazine) has been synthesized and characterized by elemental analysis, infrared, UV-Vis, and 1H NMR spectroscopy. The title compound, [Ni(C10H9N4O2S)2(C5H5N)2](C5H5N)(H2O)2 crystallizes in monoclinic system with space group P21 and Z=2. X-ray analysis revealed that Ni(II) ion exhibits a distorted octahedral geometry. The Hirshfeld surfaces are performed to study the nature of interactions and their quantitative contributions toward crystal packing. The results of spectral and thermal data suggest that the binding of nickel atom to the sulfonamidic nitrogen is in agreement with the crystal structure determination. Nickel sulfadiazine presents different antibacterial behavior against Escherichia coli and Staphylococcus aureus strains.
