A triangular gold(iminonitroxide‐2‐ide) trimer complex ( 5 ) was prepared and investigated to determine its magnetic properties. The results showed that the metalloid triradical is highly stable, even in solution under aerated conditions. The intramolecular exchange interaction of 5 was found to be positive ( J intra / k B ≈+29 K), thus showing that 5 is in a quartet ground state. In addition, a silver sandwich complex ( 5 ‐Ag + ‐ 5 ) was prepared and its electronic and magnetic properties were also clarified.
