Abstract

A new organic–inorganic hybrid material of formula 2[(CH₃) C₆N₄H₁₂] +[Pb2I6]2-. compound was obtained by slow evaporation at room temperature of a solution containing lead iodide and (NH₃) C₆N₄H₁₂ in a 1:2 molar ratio. Single crystal diffraction was carried out at 298 K and 100 K. The same P21/m monoclinic space group has been found for both temperatures. No structural difference has been noted apart from a typical increase of the cell parameters with temperature. The supramolecular structure cohesion is ensured by weak hydrogen bonding C–H···I interactions. The photoluminescence investigations reveal two distinct emission bands. The room-temperature infrared and Raman spectra are recorded. The theoretical infrared spectrum, crystal morphology and molecular orbital transition are calculated and discussed.
