Resonance Raman study of the polyiodide complex formed in the reaction of iodine with the polysulphur cyclic base 1,4,7,10,13,16-hexathiacyclooctadecane.
Resonance Raman spectroscopy has been used to study the reaction of iodine with the interesting polysulphur cyclic base, 1,4,7,10,13,16,-haxathiacyclootadecane (HTCOD). The results indicate that the complex [(HTCOD)2]+ x I5- is formed. The I5- unit exists in the form of distorted I2 linked to I3- unit which has two unequivalent I-I bonds. The v(I-I) for I2 occurs at 194 cm(-1) while for I-I, inner and outer bonds in I3- at 143 and 160 cm(-1), respectively.
