An unprecedented nonplanar structure characterizes the complex [Fe(OCH 3 ) 2 (dbm)] 12 (on the left in the picture), which contains the largest cyclic ferric cluster yet reported with chemically equivalent bridging units. It is made up of twelve high‐spin, antiferromagnetically coupled iron( III ) centers and neatly reacts with Na I or Li I templates in organic solution to give hexairon( III ) coronates (right). Fe=•, O=○, NaI or LiI=• Hdbm=dibenzoylmethane.
