An organic-inorganic hybrid cadmium chloride with face-sharing CdCl6 octahedral chains: Synthesis, crystal structure, optical and conduction mechanisms: [NH2(CH3)2]5Cd3Cl11

Abstract

Organic-inorganic cadmium halides have recently emerged as promising alternatives to conventional optoelectronic materials thanks to their fascinating physical properties. The hybrid organic-inorganic compound Penta-dimethylammonium-Undecachlorotricadmate (II) [(CH3)2NH2]5Cd3Cl11, denoted DMAPCC, was synthesized at room temperature and its optical and electrical properties were studied. The structure shows the orthorhombic system with the Cmcm space group. The Raman spectroscopy, at room temperature, confirmed the presence of organic and inorganic sub-lattices. The UV–visible confirms the disorder of the structure and the semiconducting behavior of this compound. Furthermore, the electrical measurement confirms the thermal analysis result. Indeed, the variation of exponent s indicates the overlapping small polaron tunneling (NSPT) conduction model described the two phases of this material.Keys-words: hybrid materials, Optical properties, thermal properties, electrical properties and conduction mechanism.
