The Role of Fluorine-Substituted Positions on the Phase Transition in Organic–Inorganic Hybrid Perovskite Compounds

“…Perovskites exhibit a variety of amazing physical properties due to their diverse composition and structure, such as a phase transition, dielectricity, piezoelectricity, superconductivity, and catalysis. − Therefore, perovskite compounds are one of the current hot spots in the field of material sciences. − Especially, organic–inorganic hybrid perovskites (OIHPs) have attracted tremendous research interest because of their extraordinary electronic and optical properties . In comparison with the traditional inorganic perovskites with simple and rigid structures, the OIHPs have remarkable structural diversity and controllable physical properties, which makes it possible to engender inexhaustible applications in the fields of microelectronics, energy storage, photovoltaics, etc. − From an application point of view, OIHPs with a high phase transition temperature ( T c ) are particularly important for practical applications in the military, aerospace, and construction industries under severe high-temperature conditions. − …”

Two complexes of PtIVand AuIIIwith 2,2′-dipyridylamine and 2,2′-dipyridylaminide ligands

“…analogous structural motif can be found in the known polymorph of [PtCl 4 (Hdpa)] [CÁ Á ÁC = 3.348 (7) Å and ClÁ Á ÁH = 2.76 Å ; Ha, 2011), but not in the structure of [PtCl 4 -(Hdpa)]ÁDMF (DMF is dimethylformamide; Abedi et al, 2011). The chains in (I) are connected to each other by Cl3Á Á Á contacts [the shortest ClÁ Á ÁC distance is 3.3432 (1) Å ] and by interactions between atom Cl3 and pyridine atom H4 and amine atom H1N (ClÁ Á ÁH distances of 2.93 and 2.91 Å , respectively) of a molecule in an adjacent chain.…”

“…It should be noted that, due to diminished conjugation between the pyridine rings in Hdpa, none of the previously reported structures, viz. [PtCl 4 (Hdpa)](Ha, 2011), [PtCl 4 (Hdpa)]ÁDMF(Abedi et al, 2011) or [AuCl 2 (Hdpa)]Cl(Shi & Jiang, 2006), has such interactions. The dimeric structure of (II) is further supported by ClÁ Á ÁH contacts between adjacent molecules (ClÁ Á ÁH = 2.82-2.92 Å ).…”
