While the constraints on the choice of organic cations are greatly relaxed for layered two-dimensional perovskites compared to three-dimensional perovskites, the shape of the spacer cation is still subject to limitations due to the size of the inorganic pocket between four adjacent corner-sharing octahedra. To investigate the effect of the spacer cation branching on the formation of Ruddlesden−Popper (RP) structures, we performed a comprehensive investigation of structures formed using tert-butyl ammonium (t-BA). We demonstrate that in contrast to pure bromides and pure iodides, the use of mixed halides enables the formation of the t-BA 2 PbBr 2 I 2 RP perovskite structure with the specific ordering of the bromide and iodide anions. The t-BA spacer, despite its branched and bulky shape that prevents its deeper penetration, is able to form significant H-bonds that lead to the stabilization of the RP assembly if the inorganic pocket is designed in such a way that the bromide anions occupy terminal axial positions, while the iodides occupy equatorial positions. We obtain excellent agreement between experimentally determined and theoretically predicted structures using global optimization via a minima hopping algorithm for layered perovskites, illustrating the ability to predict the structure of RP perovskites and to manipulate the perovskite structure by the rational design of the inorganic pocket.

Inorganic−organic hybrid phase transition compounds have been widely studied because of their abundant physical properties and excellent chemical tunability. In this work, two novel inorganic−organic hybrid In(III)-based phase transition compounds, (C 10 H 16 N) 2 [InBr 5 (H 2 O)] (1, C 10 H 16 N + = 4-phenylbutylammonium) and (C 6 H 14 N)[InBr 4 ] (2, C 6 H 14 N + = Nmethylpiperidinium), have been obtained and studied. Differential scanning calorimetry (DSC) tests show that 1 and 2 experience phase transitions with a T p (phase transition temperature) of 260 and 304 K, respectively. Single-crystal diffraction analysis reveals that the source of the phase transition of 1 is the displacement of (C 10 H 16 N) + cations. The reversible phase transition of 2 is triggered by the change of the disorder degree in the (C 6 H 14 N) + cations. Meanwhile, compounds 1 and 2 display distinct dielectric response behavior near T p . This study will provide valuable insights for further investigation and exploration of the novel In(III)based inorganic−organic hybrid phase transition composites.

“…The hybrid organic–inorganic materials, integrating flexible organic and inorganic units into structures, exhibit more diverse functions than conventional inorganic or organic materials, such as ferroelectric, ferroelastic, ferromagnetism, multiferroic, etc., and hence, they can be applied in the fields of sensing, dielectric switches, and communication devices. − These functions are associated with the phase transitions of materials, thus the exploration of new phase transition materials not only is instructive for exploring new physical properties but also is vitally important for designing and manufacturing functional equipment. − For example, an organic–inorganic hybrid formic material, [(CH 3 ) 2 NH 3 ]Mn(HCOO) 3 , is a multiferroic material with magnetic and electrical ordering coexistence, which is derived from the first-order phase transition and dielectric anomaly caused by the order–disorder changes of cations in the process of temperature change . Further, a 1D chain-like hybrid (C 5 H 6 N)CdCl 3 and a 2D layered hybrid (C 5 H 6 N)Cd 2 Cl 5 were synthesized by stoichiometric regulation of reactants, and both of these materials have experienced phase transitions at different temperatures caused by order–disorder changes of cations between low and high temperatures; in addition, they have obvious differences in the dielectric properties and dynamics of the organic cations, which also emphasizes the key role of dimensional modification in phase temperature and dielectric behavior of both hybrids …”

The hybrid organic–inorganic materials have received extraordinary attention from the academic community not only because of their natural chemical tunability but also because of their potential in producing exotic physical properties. However, these characteristics are usually caused by the phase transition of materials under changing of external terms, and it is crucial to fully understand their origins. Here, we research an unusual phase transition near room temperature between two ordered phases in a one-dimensional (1D) hybrid organic–inorganic material of Sb ||| -based [(CH2)3NH2S]2SbCl5 (1). This phase transition is caused by collective actions, including the primary variation in the bonds of inorganic five-coordinated tetragonal pyramids, displacement and rotation of organic and inorganic components, along with concurrent hydrogen bonds transformation. Afterward, we observe a significant dielectric anomaly at low frequencies between low and high temperatures. This attributed to the fact that two phases coexist with the lessening temperature, which means that a small number of high-temperature features remained but did not occur during the heating process. These findings offer an avenue for inventing a fresh phase transition and dielectric switch hybrid materials, which further open up the prospect for their practical application.
