Thermal property and structural molecular dynamics of organic-inorganic hybrid perovskite 1,4-butanediammonium tetrachlorocuprate.

ABSTRACT: We investigate the thermal behaviour and physical properties of the crystals of the organic inorganic hybrid perovskite [(NH₃)(CH₂)₄(NH₃)]CuCl₄. The compound's thermal stability curve as per thermogravimetric analysis exhibits a stable state up to ∼495 K, while the weight loss observed near 538 K corresponds to partial thermal decomposition. The ¹H nuclear magnetic resonance (NMR) chemical shifts for NH₃ change more significantly with temperature than those for CH₂, because the organic cation motion is enhanced at both ends of the organic chain. The ¹³C NMR chemical shifts for the 'CH₂-1' units of the chain show an anomalous change, and those for 'CH₂-2' (units closer to
