Effect of methylene chain length of perovskite-type layered [NH₃(CH₂) _n NH₃]ZnCl₄ (n = 2, 3, and 4) crystals on thermodynamic properties, structural geometry, and molecular dynamics.

ABSTRACT: The structure of organic-inorganic perovskite [NH₃(CH₂)₄NH₃]ZnCl₄ was determined; the lattice constants with monoclinic structure were determined to be a = 7.2527 Å, b = 8.1101 Å, c = 10.3842 Å, and β = 80.3436°. The crystal was almost thermally stable up to approximately 560 K. The endothermic peaks at 481 K and 506 K were assigned to the phase transition of the material. In addition, the structural characteristics and molecular dynamics of the cation were studied via magic angle spinning nuclear magnetic resonance experiments. Based on the results, the effects of the length of the CH₂ group in the cation of the [NH₃(CH₂) _n NH₃]ZnCl_4<
