Two novel organotin(IV) complexes containing phosphoric triamide ligands were synthesized using ultrasonicmethod and characterized by multinuclear (1H, 31P, 13C) NMR, infrared, ultraviolet and fluorescence spectroscopy as wellas elemental analysis. The 1H NMR spectra of complexes 1 and 2 proved that the Sn atoms adopt octahedral configurations.The nanoparticles of complexes 1 and 2were also prepared by ultrasonic method and their FE-SEM micrographs indicatedidentical spherical morphology with the particles sizes about 20-25 nm. The fluorescence spectra exhibited blue shifts forthe maximum wavelength of emission upon complexation.
