Crystal Structure, Vibrational and Electrical Properties of the Bis (phenylammonium) Hexachlorotin(IV): (C6H5NH3)2*SnCl6

The X-ray single crystal diffraction has been employed to study the crystal structure of (C6H5NH3)2SnCl6 at 298K. The crystal structure is monoclinic, space group P21/c, Z=4, a= 7.116 (5)?, b=25.304 (2)?, c=11.686 (9)? and ?=90.239 (4)?. The structure was solved from 4041 independent reflections with R1=0.0328 and wR2=0.0822 and refined with 212 parameters. The crystal is built up of separated (SnCl6)2- octahedral anions and two phenylammonium cations. These chains are hemselves interconnected by means of N-H?Cl hydrogen bonds originating from the organic cation (C6H5NH3)+. The Infrared and Raman spectra of this compound have been recorded at room temperature and discussed in relation to the crystal structure of a made-up (C6H5NH3)2SnCl6 sample. The alternative current (ac) conductivity of the compound (C6H5NH3)2SnCl6 has been measured in the temperature range 314?368 K and the frequency range 209 Hz?5MHz. The Cole- Cole (the imaginer part (Z) versus real part (Z') of impedance complex) plots are well fitted to an equivalent circuit model which consists of a parallel combination of a bulk resistance (Rp) and constant phase elements (CPE). The single semicircle indicates only one primary mechanism for the electrical conduction with in (C6H5NH3)2SnCl6.
