摘要：
Structural properties of the organic-inorganic hybrid(CHNH)CuClhave been investigated by means of x-ray powder diffraction and Rietveld analysis. A structural phase transition from Pbca to Aba2 occurs at T= 240 K, which results in a paraelectric–ferroelectric phase transition. The release of the Jahn–Teller distortion with increasing temperature toward Tis revealed by the structural analysis.
