Abstract: Hydrotalcite-like compounds (HTIs),heteropolyanions with different composetions,and their pillared products were prepared.The interactions between the layers and pillars of the pillared products were investigated by IR spectra and DTA methods. Tge results show that the M3+ions in the HTIs and the component elements of the heteropolyanions with Keggin structure, which can either exist in the tetrahedral or in the octahedral positions, have significant effects on the interactions between the layers and pillars. In addition,this interaction usually results in changes in the symmetry and relative properties of the heteropolyanions.
