Synthesis, growth, and characterisation of a novel organic–inorganic perovskite-type hybrid system based on glycine

Abstract A new organic–inorganic hybrid with the empirical formula [NH3-CH2-COOH]CdCl3.H2O has been crystallised, and the structure was solved at room temperature (system (orthorhombic), space group (Pcam), unit parameters cell (a = 7.433(10) A, b = 7.743(2) A, c = 25.346(6) A), volume 1458.76 (5) A3), Z = 8). The asymmetric unit cell consists of a combination of [Cd 0.5 Cl3]– anions, one organic +NH3(CH2)CO2H cations, and one water molecule to form a two-dimensional perovskite system. The hydrogen-bonding network ensures cohesion between these layers. The micro-Raman spectroscopy measurement technique is used to probe organic−inorganic halide perovskite vibration modes. The compound was, also, characterised using the vibrating sample magnetometer VSM and the UV-visible absorption techniques.
