On some spectroscopic properties of a layered 1,3-diammoniumpropylene tetrabromocadmate hybrid crystal

On the Structural Phase Transition in a Perovskite-Type Diaminopropanetetrachlorocuprate(II) NH3(CH2)3NH3CuCl4 Crystal

“…Among them an interesting group of hybrid compounds are perovskite-type layered compounds containing propylenediammonium cations (NH 3 (CH 2 ) 3 NH 3 ) and layered metal-halogen anionic sublattices. Up to now, structural phase transitions were found in the case of crystals containing propylenediammonium cations in [NH 3 (CH 2 ) 3 NH 3 ]CdCl 4 -phase transition at 375 K [1][2][3] and [NH 3 (CH 2 ) 3 NH 3 ]CdBr 4 -phase transitions at 326 K and 385 K [4,5]. Two structural phase transitions were found at 305 K and 337 K in [NH 3 (CH 2 ) 3 NH 3 ]MnCl 4 [6].…”

Experimental (FTIR, Raman, UV–visible and PL) and theoretical (DFT and TDDFT) studies on bis(8–hydroxyquinolinium) tetrachlorocobaltate(II) compound

“…In fact they present interesting properties excellent magnetic, luminescence, nonlinear optical (NLO), catalytic, electrical and ferroelectric properties [1][2][3][4][5][6][7][8]. The general formula in this family is R 2 [MX 4 ] where M = transition metal, X = Cl, Br, I and R is an organic cation.…”

Physicochemical Properties and Structural Dynamics of Organic–Inorganic Hybrid Perovskite [NH3(CH2)3NH3]ZnX4 (X=Cl and Br) Crystals

“…Organic-inorganic compounds based on two-dimensional (2D) hybrid perovskites, particularly [ 4 have been extensively studied because of their relative stability and potential applications. [6][7][8][9][10][11] The physical and chemical properties of the organic-inorganic hybrid perovskites depend on the characteristics of the organic cations, geometry of the inorganic anions (metal halide ions; (BX 6 ) 2− or (BX 4 ) 2− ), and reaction stoichiometry. [1][2][3][12][13][14][15][16][17][18] For B=Mn, Cu, or Cd, the structure is consists of the corner shared octahedral (BX 6 ) 2− alternated with organic layers.…”
