The tinmetal mixed hydroxides CaSn(OH)6, MnSn(OH)6, CoSn(OH)6, and ZnSn(OH)6, with cubic morphologies, were prepared using a coprecipitation method; they were subsequently transformed into the corresponding tinmetal mixed oxides by calcination at 600900 °C. The crystalline structures and the morphologies of the various samples at each calcination step (just prepared, dried at 110 °C, and calcined at 600 and 900 °C) were systematically evaluated by X-ray diffractometry, scanning electron microscopy, transmission electron microscopy, and X-ray absorption fine structure analyses. The cubic shapes of the CaSn(OH)6 and ZnSn(OH)6 nanoparticles were maintained after calcination of them at 600 and 900 °C, while those of MnSn(OH)6 and CoSn(OH)6 ones were not maintained after calcination of them.
