[Se6I+]n·n[AsF6–] has been prepared quantitatively and its crystalstructure determined by single crystalX-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.
定量制备了[Se 6 I + ] n · n [AsF 6 – ],并通过单晶X射线衍射确定了其晶体结构。阳离子由[Se 6 I + ] n链组成,椅子构象的六硒环通过两个弱的[2.736(3)Å]外环1,4轴向硒碘键与两个相邻的六硒环相连。 。
