Résumé en anglais

The amino acid copper chlorides [NH3C2H4CO2H]2 CuCl4 is a new member of the family of organic-inorganic hybrid like perovskite system. This compound crystallizes in the monoclinic space group C2/c with unit cell parameters a = 25.1209 (3) Å, b = 7.7432 (2) Å, c = 7.4130 (2) Å, β = 105.293 (2)° and Z = 4. The molecule formula consists of a combination of [CuCl4]2– anions and two twisted organic [NH3(CH2)2CO2H]+ cations to form a two-dimensional perovskite system. Three dimensional hydrogen – bonding network is assuring the cohesion between these layers to stabilize the crystal. The micro-Raman spectroscopy measurement technique is used to probe organic−inorganic halide perovskite vibration modes and to study the effect of laser beam power on the intensity of Raman lines.< Réduire
