Abstract:   (2209 Views)

In this research, poly halogene-chalcogene
SeCI2lCI was synthesised and the crystal structure was
determint:d by !l singk ;ryslal X-ray diffraction method.
This compound formed at temperature ranges from
70-1S00C as ruby-red color and crystallizes in monoclinic
crystal sys tem, space group P2t/c with 4 molecules per unit
cell. Lattice parameters of the compound are:
a = 6.088 A b = 6.555 A c = 16.032 A
a=y=90° f3 = 98.02° v = 633.5 A'
In addition, n .T.A analysis of SeCI2ICI crystals at
tempe rature ranges from _70°C to 194°C and IR studies in
the lower range of 700cm'} and Raman studies in the lower
range of SOOcm·1 were also carried out.
