A new organic–inorganic hybrid with the empirical formula [NH3single bondCH2single bondCOOH]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) Å, b = 7.743(2) Å, c = 25.346(6) Å), volume 1458.76 (5) Å3), 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.
