The preparation and X-ray crystal structure of [Se6I+]n·n[AsF6–] containing the catena-poly[cyclohexaselenium(I)-4 : 1-µ-iodo] cation
Abstract
[Se6I+]n·n[AsF6–] has been prepared quantitatively and its crystal structure determined by single crystal X-ray diffracticn; the cation consists of strands of [Se6I+]n, and the hexaselenium rings, of a chair conformation, are joined to two neighbouring hexaselenium rings by two weak [2.736(3)Å] exocyclic 1,4 axial selenium–iodine bonds.
