Variable Temperature Behaviour of the Hybrid Double Perovskite MA<sub>2</sub>KBiCl<sub>6</sub>
Perovskite-related materials show very promising properties in many fields. Pb-free perovskites are particularly interesting, because of the toxicity of Pb. In this study, hybrid double perovskite MA<sub>2</sub>KBiCl<sub>6</sub> (MA = methylammonium cation) was found to have...

| description | Perovskite-related materials show very promising properties in many fields. Pb-free perovskites are particularly interesting, because of the toxicity of Pb. In this study, hybrid double perovskite MA<sub>2</sub>KBiCl<sub>6</sub> (MA = methylammonium cation) was found to have interesting variable temperature behaviours. Both variable temperature single crystal X-ray diffraction, synchrotron powder diffraction, and Raman spectroscopy were conducted to reveal a rhombohedral to cubic phase transition at around 330 K and an order to disorder transition for inorganic cage below 210 K. |
