Filling The Gap in The Metallacrown Family:

The 9‐MC‐3 Chromium Metallacrown

A long‐sought missing complex in the metallacrown family is found by the synthesis of 9‐MC‐3 Chromium Metallacrown. This fills the gap and complete this class of compounds important in molecular recognition, catalysis, and magneto chemistry. While metallacrowns are usually built via self‐assembly reactions, the solvothermal reaction paves the way for new kinetically and thermodynamically stable metallacrowns.
