摘要：

The [C12H12N](2)BiCl5 compound crystallised in the monoclinic system with space group P2(1)/n with a = 11.243(5), b = 9.173(5), c = 26.667(5) angstrom, beta = 92.195(5)degrees and Z= 4. The average density value, rho(m)= 1.694 cm(-3) is in agreement with the calculated one, rho(x) = 1.756 cm(-3). The atomic arrangement can be described as an alternation of organic and inorganic layers. The anionic layer is built up of octahedral [Bi2Cl10](4-). The organic layers are arranged in sandwich between the anionic ones. The crystal packing is governed by means of the ionic N-H center dot center dot center dot Cl hydrogen bonds, forming a three dimensional network. The nature of the distortion of the inorganic polyhedra has been studied and can be attributed to the stereo activity of the Bi(III) lone electron pair. The infrared spectra was recorded in the 4000-400 cm(-1) frequency region and the Raman spectra was recorded in the external region of the anionic sublattice vibration 500-50 cm(-1) at various temperatures 298-428 K.
