The molecular ion [B12Cl11]− displays two seemingly incompatible sides, a negative and a positive one, just like the goddess Helja in Norse mythology. Physically, [B12Cl11]− is an anion but it shows chemical reactivity known for highly electrophilic cations. In their Communication (DOI: 10.1002/anie.201702237), S. Grabowsky, J. Warneke et al. report that the electrophilicity of [B12Cl11]− is so high that the noble gases Kr and Xe are bonded spontaneously at room temperature in a reaction that is typical of superelectrophiles.
