Reactions of Zinc(II) and Manganese(II) (1-Hydroxyethylidene)diphosphonates with Aqueous Solution of 3-Aminopropyltriethoxysilane.

Zinc(II) bis(3-aminiumpropylsilsesquioxane)(1-hydroxyethylidene)diphosphonate tetrahydrate and manganese(II) bis(3-aminiumpropylsilsesquioxane)(1-hydroxyethylidene)diphosphonate trihydrate were obtained by the reactions of aqueous solution of 3-aminopropyltriethoxysilane with (1-hydroxyethylidene)diphosphonates of zinc(II) H2ZnL·2H2O and manganese(II) H2MnL·3H2O. The synthesized compounds were studied by the methods of elemental, thermal, and X-ray phase analysis, IR spectroscopy, and scanning electron microscopy. The specific surface areas of the initial xerogels and products of their thermal decomposition were measured. [ABSTRACT FROM AUTHOR]
