Abstract:
Two new nanosized organotin(IV) complexes 1 and 2 were synthesized by ultrasonic method from the reaction of SnCl2(H2O)2 and SnCl(Ph)3 with phosphazene ligand p-CH3-C6H4- SO2N=P(NC4H8O)3. The two complexes were characterized by 1H, 13C, 31P{1H} NMR, FT–IR, fluorescence, FE–SEM microscopy and elemental analysis. The 31P{1H} NMR spectra reveal that the phosphorus chemical shift of complex 1 appears at slightly up field region (14.44 ppm) compared with that of 2 (14.46 ppm) confirming the P atom is slightly more shielded in 1 than in 2. The peak integralsin the 1H NMR spectra show that the Sn atoms adopt octahedral conformations in both complexes 1 and 2. The FE-SEM images of complexes 1 and 2 indicate that the particles are spherical in morphology with their average particles sizes are approximately within the range of 25-40 nm.
