Structure and morphology of nano-sized particles of tin(IV) oxide obtained by oxidative thermolysis of tin(II) oxalate SnC2O4 were studied by powder X-ray diffraction and transmission electron microscopy. The X-ray diffraction pattern corresponds to cassiterite SnO2; however, a strong broadening and a decrease in height of 110 peak are observed. Based on transmission electron microscopy data, it was assumed that planar defects are present in the SnO2 structure. Such defects are observed in nsutite γ-MnO2, the structure of which is disordered and represents an intergrowth of pyrolusite β-MnO2 and ramsdellite R-MnO2 structures. For the first time, a quantitative assessment of such defects in the SnO2 structure was carried out by calculating X-ray diffraction patterns based on statistical models of 1D disordered nanocrystals.
