N2 - Perovskite Layer compounds with the general formula (CnH2n+1NH3)2MX4 or [NH3(CH2)nNH3] MX4 where M is a divalent metal atom and X an halogen (M = Cu, Mn, Zn, Co, Cd⋯) (X = Cl, Br⋯) are lamellar type structures with a particular properties due to synergy between organic and inorganic parts. In this work, the synthesis and the structure by X-ray powder diffraction of the compound [NH3-(CH2)8-NH3] 2CuCl4 are presented. The studied compound crystallize in the monoclinic system with cell parameters: a= 5.3230(15) Å, b= 13.4714 (40) Å, c= 5.1414 (13) Å, β = 91.832 (32)°. The compound is also investigated by means of Infra-Red spectroscopy, Electron Paramagnetic Resonance (Electron Spin Resonance ESR) and UV-Visible spectroscopy. The ESR study shows a typical signal for distorted octahedral site and for a Ferro Magnetic Resonance (FMR). The absorption spectrum of UV-Visible spectroscopy shows bands due to Charge Transfer Transitions from the ligand orbitals (pσ and pπ) to the half-occupied d orbital.
