Preparation, molecular structure, vibrational and photoluminescence study of a novel compound based chlorocadmate(II) material

Abstract

In the present work, we synthesized a new hybrid compound, (C6H10N2)2 Cd3Cl10. The crystal structure, vibrational and photoluminescence properties of the compound were studied. The structure can be described by the alternation of two different cationic-anionic layers. It consists of Cd3Cl10 dimers anions and bis Orthophenylenediammonium (C6H10N2) cations, which are connected via N-H···Cl hydrogen bonds forming a chain network. Furthermore, the 3D Hirshfild surfaces and the associated 2D fingerprint plots were investigated for intermolecular interactions in the molecule. The X ray powder is in agreement with the x ray structure. The Infrared Spectrum recorded in the 4000-400 cm-1 frequency region was compared with those found for homologous compounds in the literature. Solid state 13C NMR spectrum shows three signals, confirming the solid state structure determined by X-ray diffraction. Finally the characteristic exciton peaks in absorption spectra are located at 250 and 494 nm and the photoluminescence measurements showed one peak at around 2.06 eV.
