The rutile-type SnO{sub 2} nanocondensates as condensed by Nd-YAG laser ablation on Sn target under oxygen background gas were characterized by analytical electron microscopy to have {l_brace}110{r_brace}, {l_brace}100{r_brace} and {l_brace}101{r_brace} facets, which are beneficial for {l_brace}{approx}hkl{r_brace} vicinal attachment to form edge dislocations, faults and twinned bicrystals. The {l_brace}011{r_brace}-interface relaxation, by shearing along <011> directions, accounts for a rather high density of edge dislocations near the twin boundary thus formed. The rutile-type SnO{sub 2} could be alternatively transformed from orthorhombic CaCl{sub 2}-type structure (denoted as o) following parallel crystallographic relationship (01-bar 1){sub r}//(01-bar 1){sub o}; [111]{sub r}//[111]{sub o}, and full of commensurate superstructures and twins parallel to (011) of both phases.
