Crystal Structure, Dielectric Characteristics and Conduction Mechanism of a New Hybrid Material, Tetra(Phenylpiperazinium) Decachlorotriplumbate(II)

Monocrystalline (C10H15N2)(4)Pb3Cl10 was obtained via an aqueous solution reaction and characterized by single-crystal X-ray diffraction technique, elemental analyses, IR spectroscopy, UV-Vis spectrum, photoluminescence properties and thermal analysis. Structural characterization reveals that the title compound is built from [Pb3Cl10](4-) units sharing Cl2 atom to form 2-D [Pb3Cl10] (n) (4n-) layers, these anions are linked to the organic cations via N-H center dot center dot center dot Cl and C-H center dot center dot center dot Cl hydrogen bonding. Moreover, dielectric relaxation spectroscopy has also been determined to show different molecular motions. Measurements of AC conductivity as a function of frequency at different temperatures indicated the hopping conduction mechanism.
