Three similar layered perovskite-type organic-inorganic hybrids were synthesized with selecting CuCl2 as the main inorganic component and by altering the organic component via liquid phase reaction.The inorganic component,organic component and crystalloid structure of three hybrids were characterized and analyzed by scanning electron microscope(SEM),X-ray diffraction(XRD) and FT-IR spectra.The experimental results indicated that the layered structures displayed more clearly when the organic components were alkyl amine rather than aniline.The formation of layered structure was probably related with the length of carbon chain and the structure of benzene ring.Since the interaction between the organic amine and inorganic octahedral truss (［CuCl6］4-) was the van der Waals force(mainly expressed as the hydrogen bonding H—N……Cl),the structure of the organic components played an important role in the formation of layer structured perovskite-type hybrids.According to Bragg’s equation and an approximative method,the distance of the adjacent layered perovskites(d) of three compounds with cations of propylammonium,butylammonium and phenylammonium were calculated to be 12.31,15.39,14.82?,respectively.
