The Front Cover shows a rare tetraselenide obtained from dimerized diselenides through chalcogen bonding by sterically controlled oxidation of mesoionic selone using a copper(II) salt. The picture represents the formation of single crystals form a concentrated solution with a unique structural aggregation along with unusual bonding features. More information can be found in the Full Paper by M. Vaddamanu and G. Prabusankar.

前封面：扭曲二硒化物中硫族元素键合诱导的四硒化物（欧洲J.无机化学杂志，25/2020年）

前封面显示了一种稀有的四硒化物，它是通过使用铜（II）盐通过空间控制氧化中子selone的硫族元素键而从二聚二硒化物获得的。图片代表了具有独特结构聚集以及异常键合特征的浓缩溶液形式的单晶形成。可以在M. Vaddamanu和G. Prabusankar撰写的《全文》中找到更多信息。
