The synthesis and low-temperature single crystal X-ray structure of the charge-transfer complex ([9]aneS3)2(l2)4([9]aneS3= 1,4,7-trithiacyclononane)

Abstract

Reaction of [9]aneS₃(1,4,7-trithiacyclononane) and I₂ in cold CH₂Cl₂ results in the formation of 1 :1 and 1 : 2 adducts; the single crystal X-ray structure of the 1 :2 adduct ([9]aneS₃)₃(I₂d2)₄ shows an unusual polymeric structure with I₂ bridging [9]aneS₃ thioether units.
