Abstract
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.
