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 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] +·I 5 − is formed. The I 5 − unit exists in the form of distorted I 2 linked to I...

Zusammenfassung: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] +·I 5 − is formed. The I 5 − unit exists in the form of distorted I 2 linked to I 3 − unit which has two unequivalent II bonds. The ν(II) for I 2 occurs at 194 cm −1 while for II, inner and outer bonds in I 3 − at 143 and 160 cm −1, respectively.
