Structural Characterization and Infrared and Electrical Properties of the New Inorganic-Organic Hybrid Compound [N(C3H7)‎4]2[Hg2Cl6]

Abstract EN

New inorganic-organic hybrid [(C3H7)4N]2Hg2Cl6 compound was obtained and characterised by single-crystal X-ray diffraction, infrared, and impedance spectroscopy.

The latter crystallizes in the monoclinic system (space group C 2/c, Z=8) with the following unit cell dimensions: a=18.489(1) Å, b=13.0419(6) Å, c=29.162(2) Å, and β=91.686∘(2).

Besides, its structure was solved using 84860 independent reflections leading to R=0.038.

Electrical properties of the material were studied using impedance spectroscopic technique at different temperatures in the frequency range of 209 Hz to 5 MHz.

Detailed analysis of the impedance spectrum suggested that the electrical properties of the material are strongly temperature-dependent.

The Nyquist plots clearly showed the presence of bulk and grain boundary effect in the compound.
