Abstract
Resonance Raman spectroscopy has been used to study the reaction of iodine with the interesting polysulphur cyclic base, 1,4,7, 10,13,16,-haxathiacycl ootadecane (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 t o I-3(-) unit which has two unequivalent I-I bonds. The v(I-I) for I-2 occu rs at 194 cm(-1) while for I-I, inner and outer bonds in I-3(-) at 143 and 160 cm(-1), respectively. (C) 2000 Elsevier Science B.V. All rights reserve d.
