Following the building principles of crown ethers for cation encapsulation, inverse crowns are rings of metals that bind anions. Now a redox-active inverse crown ether featuring Na+ cations and Mg0 has been shown to reduce epoxides, N2O, S8 or O2 by combining anion complexation by the ring of metal cations with the reducing power of Mg0.
