Pyrolysis experiments were carried out with Sn{sub 4}R{sub 4}O{sub 6} (R=methyl (1), butyl (2) and phenyl (3)). The thermal behaviour of the organotin oxides was studied by Thermogravimetric Analysis (TG) with simultaneous Differential Thermal Analysis (DTA) and the residues obtained after decomposition were characterised by X-ray electron probe microanalysis (EPMA), Scanning Electron Microscopy (SEM), X-ray diffraction and {sup 119}Sn Moessbauer spectroscopy. The results have shown that the methyl derivative is the best precursor, producing nanoparticles of pure phase rutile-type tetragonal SnO{sub 2} in O{sub 2} with a yield up to 90%.
