Synthesis and characterization of a new organotin(IV) complex as a new precursor for preparation SnO2 nanoparticles

An efficient method was developed for the preparation of a new hexaorganostannoxane complex, [Me(12)Sn(6)C(l)2(N-3)(2)(DMSO)(2)O-4] (1). The prepared complex was characterized by infrared, H-1, C-13, and Sn-119 NMR spectroscopes and elemental analysis. The structure of 1 was determined by single-crystal X-ray diffraction. Complex 1 was utilized as a precursor for the preparation of SnO2 nanoparticles by direct thermal decomposition at 500 degrees C in air. The nanostructure of SnO2 was characterized by scanning electron microscopy and X-ray powder diffraction. The SnO2 core showed a band gap of similar to 3.91 eV. The SnO2 nanoparticles show stable photoluminescence (PL) with an emission centered at 561 nm.
