Abstract
An opportunity for direct mechanochemical synthesis of double tin and alkaline earth metal hydroxides via two procedures was demonstrated. The latter were based on reactions of chloride (IV) pentahydrate and alkaline earth metal hydroxides or salts (in the latter case, upon simultaneous action of NaOH). It was possible to synthesize Mg/Sn layered double hydroxide using only the first procedure. Calcium, strontium, and barium compounds were synthesised by both procedures. The X-ray diffraction patterns of double hydroxides MSn(OH)6
(M = Ca, Sr, Ba) are in good agreement with structural data acquired in early research works and presented in X-ray databases. The products contain trace carbonate impurities, which is related to their presence in the initial reagents.
