In this issue of Chem, Kinjo and Feng report the synthesis of a cyclotriborate trianion (B₃R₆³⁻), a highly charged boron ring system with discrete two-center two-electron bonds. With three contiguous borates, the B₃³⁻ core of the feature compound defies Coulomb’s law and represents the first homocyclic boron analog of the ubiquitous cyclopropane. The remarkable stability enabled full characterization and opens new vistas in the field of multiply charged boron ions.

环三硼酸盐三阴离子


在本期的 Chem 杂志上，Kinjo 和 Feng 报道了环三硼酸盐三阴离子 （B₃R₆³⁻） 的合成，这是一种具有离散双中心双电子键的高电荷硼环系统。特征化合物的 B₃³⁻ 核心具有三个连续的硼酸盐，违背了库仑定律，代表了无处不在的环丙烷的第一个同环硼类似物。卓越的稳定性使全面表征成为可能，并为多电荷硼离子领域开辟了新的前景。
