An organo-mineral nanohybrid material in which the organic moiety is interleaved inside the inorganic lamella was prepared by using phenoxyacetate anions as a guest in the Mg-Al-layered double hydroxide lamella (as an inorganic host) by the self-assembly technique, anion exchange and the reconstruction methods. The powder XRD patterns of the resulted materials show that the basal spacing of the Mg-AI-layered double hydroxide with carbonate as the counter anions expanded from 7.7 ? to around 16.6 ? in the nanohybrid materials. IR studies show that the absorption bands of the resulting materials correspond to the characteristic functional groups of the host and the guest structures. When the two results are taken together, the expansion can be attributed to the intercalation of the phenoxyacetic acid in the inorganic interlamella for the formation of the nanohybrid material. The intercalation of phenoxyacetate anions was also confirmed by thermogravimetric analysis (TG).
