Abstract: New materials were prepared by intercalation reactions between layered zirconium glycine-N,N-dimethylphosphonate (ZGDMP) and non-aromatic heterocyclic amines: piperazine, piperidine, and morpholine. X-ray powder diffraction patterns showed that the entrance of piperazine, piperidine, and morpholine caused an interlayer expansion of 0.40 nm, 0.66 nm, and 0.67 nm, respectively. The infrared spectra were in agreement with an acid-base reaction, involving layered acid host COOH of ZGDMP and basic center atoms of guest molecules. Thermogravimetric curves revealed thermal stability of the intercalation compounds and content of the inserted amine molecules. These results indicate that non-aromatic heterocyclic amines were intercalated into the galleries of host ZGDMP.
