Abstract

Solutions of Sn(OR)4 and R'Sn(OR)3 with different amounts of alkali and alkaline earth metal alkoxides, MI(OR) and MII(OR)2 respectively, have been prepared. Slow evaporation of the solvent resulted in the crystallization of mixed metal alkoxide compounds. Solid state structures have been determined for two examples: K3H[Sn(O/Pr)6]2 and Na2[iPrSn(OiPr)5]·5iPrOH. Solutions as well as solids have been hydrolyzed by moisture. The thermal behaviour of the resulting amorphous powders was investigated by TG, DTA and XRD up to 1000°C in argon atmosphere. The structural evolution during the solid state step mainly depends on the nature and amount of the mono- and bivalent cations. The different influence of both parameters is described.

17. The discrepancy may also be due to a partial votalization of K2O as a result of the thermal degradation of an other ternary phase. Its total votalization should give a weight loss of more than 50%.Google Scholar
18. Systematical investigations have shown, that stronger drying conditions (24h at 300°C in vacuum) will reduce the difference between calculated and observed weight loss. In this case, the initial weight loss is much less pronounced than by the drying procedure used in this investigation.Google Scholar
