The first fluorinated cationic eight-membered chalcogen-nitrogen ring system, containing Te and Se, [F[graphic ommitted]]+[TeF5]- has been prepared by reacting Se(NSO)2 with TeF4; its molecular structure has been determined by X-ray crystallography (as a byproduct [Se2N2S]2[TeF5]2 was isolated).
通过 Se(NSO)2 与 TeF4 反应,制备出了第一个含
氟阳离子八元查耳根氮环系统,即[F[图形省略]]+[TeF5]-;其分子结构已通过 X 射线晶体学确定(作为副产品,分离出了[Se2N2S]2[TeF5]2)。
