| Abstract: | Structural properties of the organic-inorganic hybrid (C2H5NH3)2CuCl4 (EA2CuCl4) have been investigated by means of x-ray powder diffraction and Rietveld analysis. A structural phase transition from Pbca to Aba2 occurs at T4=240 K, which results in a paraelectric-ferroelectric phase transition. The release of the Jahn-Teller distortion with increasing temperature toward T4 is revealed by the structural analysis. |
