Exchange of silicate anions into hydrotalcite-type materials leads to the ready formation of well-ordered two-dimensional silicate sheets. The combined evidence from diffraction, NMR, and IR allows for a global identification of the reaction product. Its structure probably consists of positively charged brucitelike layers intercalated with puckered, silicic-acid-type macroanions.
