The Cu(II) and Cd(II) complexes have been synthesized by the reaction of copper(II) and cadmium(II) salts with sulfadiazine (sdz) and 1,2-diaminopropane (dap) as ligands under room temperature conditions using methanol as the solvent. Both complexes were characterized by elemental analysis (CHN), Fourier-transformed infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and powder X-ray diffraction (PXRD) techniques. Single crystal X-ray analysis reveals that two new complexes, [Cu(dap)2(sdz)2] (1) and [Cd(dap)2(sdz)]·H2O·sdz (2) are a mononuclear structure and the Cu(II) ion exhibits a distorted octahedral coordination geometry. In contrast, the Cd(II) ion shows distorted square pyramid geometry. Moreover, the fluorescence properties of the complex 1, which was compared with the sdz ligand, indicate that it has lower fluorescence emission at 320 nm. In contrast, complex 2 showed high-intensity emission, which can serve as potential applications.
