Chloride perovskite layer compounds of [NH3-(CH2)n-NH3]MnCl4 formula

Solid State Communications, 1976
Abstract [NH3-(CH2)n-NH3]MnCl4 compounds with n = 2, …, 5 are chloride perovskite layer structures. The room temperature phase of members with odd numbers of carbon atoms is orthorhombic, whereas even numbers lead to monoclinic structures. Structural phase transitions were found in all compounds with n > 2.

Magnetization measurements on quasi-two-dimensional spin systems (CH2)n(NH3)2MnCl4

Physica B+C, 1977
Abstract The biammonium compounds (CH2)n(NH3)2MNCl4 form quasi-dimensional antiferromagnetic layer compounds, which are similar to the monoammonium compounds. Especially for n = 3 sharp spin-flop transitions are observed. The magnetization as a function of temperature and field was measured.

Metastable reactions in small cluster ions: (CO2)n+, (NH3)2H+ and (H2O)2H+

International Journal of Mass Spectrometry and Ion Physics, 1983
Abstract Pure mestastable transitions have been observed for loss of CO2 from (CO2)n+ for n = 2,3,4,5; for loss of NH3 from (NH3)2H+·; and for loss of H2O from (H2O)2H+. The experiments were performed in a high resolution reverse geometry instrument (V.G.

Dielectric properties of (CnH2n+1NH3)2CdCl4 and (NH3(CH2)nNH3)CdCl4 perovskite layer compounds

Solid State Communications, 1976
Abstract The dielectric properties of (CH3NH3)2CdCl4, NH3(CH2)3NH3.CdCl4 and NH3(CH2)5NH3.CdCl4 single crystals as well as of (CnH2n+1NH3)2CdCl4 (n = 1, 2, 3) and (NH3(CH2)nNH3)CdCl4 (n = 2,3,4,5) pressed powder pellets were investigated as a function of temperature between 77 and 373°K and significant dielectric anomalies were found to occur at ...
