Thermal property, structural characterization, and physical property of cation and anion in organic–inorganic perovskite [(CH2)3(NH3)2]CdCl4 crystal

Physicochemical Property Investigations of Perovskite-Type Layer Crystals [NH3(CH2)nNH3]CdCl4 (n = 2, 3, and 4) as a Function of Length n of CH2

“…The synthesis and characterization of [NH 3 (CH 2 ) 2 NH 3 ]­CdCl 4 with n = 2 were first discussed by Battaglia et al Subsequently, the X-ray results for this crystal structure at 298 K were reported by Lamhamdi et al The phase transition at 375 K for the [NH 3 (CH 2 ) 3 NH 3 ]­CdCl 4 crystal with n = 3 is reversible and continuous, according to previous dielectric and optical studies. , In addition, the structural, thermal, and vibrational properties as well as molecular motions have been characterized by Staskieqicz et al Recently, the physicochemical properties of this crystal were reported by our group . In the case of n = 4, the thermodynamic and crystallographic characters of the phase transitions for NH 3 (CH 2 ) 4 NH 3 CdCl 4 were studied, and the crystal structure in each phase was discussed from X-ray diffraction measurements. , However, despite various potential applications, there have been limited studies on compounds containing Cd.…”

Thermal, ferroelastic, and structural properties near phase transitions of organic–inorganic perovskite type [NH3(CH2)3NH3]CdBr4 crystals

“…We compared the physical properties of the previously reported [(NH 3 )(CH 2 ) 3 (NH 3 )]CdCl 4 crystals, 38 and those of [NH 3 (CH 2 ) 3 NH 3 ]CdBr 4 examined in this study. This is summarized in Table 1 .…”

Effect of methylene chain length of perovskite-type layered [NH3(CH2)nNH3]ZnCl4 (n = 2, 3, and 4) crystals on thermodynamic properties, structural geometry, and molecular dynamics

“…The 1 H NMR chemical shis were observed to be temperature-independent, which implies that the environment around 1 H does not change with temperature. However, above 380 K, the 1 The 1 H MAS NMR spectra were measured with several delay times at each given temperature. The plot of spectral intensities against the delay times is described by a single exponential function.…”

“…Organic–inorganic hybrid compounds with perovskite structures have been extensively investigated in recent years. 1 An interesting class of compounds with perovskite structures is the diammonium series, which forms layered perovskite halogen salts, as well as the monoammonium series, which has the formula [C n H 2 n +1 NH 3 ] 2 MX 4 ( n = 2, 3, …; M = Mn, Co, Cu, Zn, Cd, X = Cl, Br). 2–14 The diammonium series [NH 3 (CH 2 ) n NH 3 ]MX 4 has been studied because of its H-bonds and excellent stability.…”
