The title compound was prepared by the solid state reaction of stoichiometric amounts of CdCl2·H2O and 4 nitroaniline . The crystal used for X ray analysis was obtained by slow evaporation of an ethanol aqueous solution of the solid state reaction at room temperature. The structure of compound was characterized by X ray diffraction analysis. The crystal belongs to orthorhombic, space group Pbca, a=0.77864(7)nm,b=0.72547(6)nm,c=3.3126(2)nm,Z=4,V=1.8712(3)nm3,Dc=1.890g·cm-3,μ=1.763mm-1,F(000)=1048,R=0.0300,wR=0.0697. The title compound is a typical two dimensional organic intercalated compound. The inorganic layers of the compound are formed by CdCl6 octahedra sharing corner Cl atoms (i.e. catena poly[dihlorocadmium di μ chloro]). The organic ammonium cations are intercalated between every two metal halogen layers and formed the organic layers of the compound through hydrogen bonding.
