Synthesis, crystal structure and electrical properties of the new organic-inorganic hybrid compound bis(1-chlorido-4-aminopyridinium) octachlorodiantimoinate
Abstract
Bis(1-chlorido-4-aminopyridinium) octachlorodiantimoinate has been synthesized and characterized by a single-crystal X-ray diffraction at 296 K and impedance spectroscopy. At room temperature, the title compound is crystallized in the triclinic system (P 1 ̅ space group) with Z = 2 and the following unit cell dimensions: a = 7.919 (1) Å, b = 9.624 (1) Å, c = 17.692 (3) Å, α = 101.81 (1)°, β = 95.12 (1)°and γ = 112.48 (1)°. The crystal structure of the [C10H12Cl2N4]Sb2Cl8 compound is built of two un-equivalent monoprotonated cations [C5H6N2Cl] + and two un-equivalent tetrachloroantimonate (III) anions noted which are [Sb(1)Cl4]- and [Sb(2)Cl4]-. The arrangement of this compound can be described by an alternation of organic and inorganic layers stacked along [010] direction. The cohesion of compound entities is ensured by hydrogen bonding (N-H…. Cl) and Van Der Waals interaction (C-H…. Cl). The temperature dependence of the σdc conductivity exhibits an Arrhenius type behavior described by the following expression σdc T = Aexp(-Ea/kβT). The Ac conductivity and the dielectric loss suggest that the correlated barrier hopping is the appropriate model for the conduction mechanism.
