Abstract
The present research work reports the study on crystal structure, vibrational spectroscopy and thermal analysis of organic-inorganic hybrid compound (C6H5(CH2)(2)NH3)(2)CdCl4. Single crystals of bis(phenethylammonium) tetrachlorocadmate ((C6H5(CH2)(2)NH3)(2)CdCl4 (PEA-Cd) were obtained by diffusion at room temperature. This compound crystallizes in the orthorhombic space group C2cb with unit cell parameters a = 7.4444(2) angstrom, b = 38.8965(3) angstrom, c = 7.3737(2) angstrom and Z = 4. Single crystal structure has been solved and refined to R = 0.036 and wR = 0.092. The structure consists of an extended [CdCl4](2-) network and two [C6H5(CH2)(2)NH3](+) cations to form a two-dimensional perovskite system. The infrared (IR) spectrum of the title compound was recorded at room temperature. Differential scanning calorimetry (DSC) was used to investigate the phase transition; this compound exhibits a reversible single solid-solid phase transition.
