Formation of covalently-linked MSils. (a) FT-IR spectrum of MSil-OH, MSil-C16 and MSil-Ph show annotated characteristic stretching vibrations. (b) XRD patterns of MSil-OH, MSil-C16 and MSil-Ph (Inset: ICDD XRD pattern for Si4Mg3O12(OH)2, magnesium silicates hydrates, PDF card # 00–019-0,770) with crystallographic reflections assignment that show the formation of layered structures.
