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. © 2013 a. oueslati et al.
