by systematic characterizations. This composite revealed a reversible first-order isostructural phase transition from space group P-1 (Phase II) to space group P-1 (Phase I) at round T = 358 K. The phase transition can be ascribed to the order–disorder transition of the 1,10-Diaminodecane cations. It is known that the interesting electronic and optical properties in this family are dominated by the inorganic parts. The phase transition observed in this work arises from the organic parts. One of the main objectives is to forge a relationship between structural and thermal properties. Thus, adapting the organic fragments can lead to new multifunctional materials. A more in-depth analysis of the structural properties demonstrates the role played by the organic parts in the phase transition shown by the titled compound.
