Structural characterization and infrared and electrical properties of the new inorganic-organic hybrid compound [N(C ₃H ₇) ₄] ₂ [Hg ₂Cl ₆]

New inorganic-organic hybrid [(C ₃H ₇) ₄N] ₂Hg ₂Cl ₆ 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.
