A new perovskite like system [NH3-(CH2)10-NH3] ZnCl4, has been synthesized and characterized by single crystal X-ray diffraction, thermal analysis and infrared spectroscopic study. This compound crystallize in a triclinic space group P-1, with the unit cell parameters a=7.294(1), b=10.058(9) Å, c=12.812(1) Å, α = 90, 89(2), β = 101, 21(1), γ = 92, 40(3) and Z=2. The final R factor is 0,082. The structure of this compound might be described as layered with two parallel anionic and cationic layers. The first layer is composed by isolated distorted tetrahedral (ZnCl4)2- and the second layer of [NH3-(CH2)x-NH3]2+. Network hydrogen - bonding assures the cohesion between these layers and stabilizes the crystal. The structure shows the existence of a conformational disorder of the organic chains between " trans " and " twisted " states. The thermal analysis by DSC shows that the 2C10ZnCl4 perovskite presents reversible phase transition.Read less <
