A series of four unprecedented heterometallic metallagermsesquioxanes were synthesized. Their cage‐like architectures have a unique type of molecular topology consisting of the hexairon oxo {Fe 6 O 19 } core surrounded in a triangular manner by three cyclic germoxanolates [PhGe(O)O] 5 . This structural organization induces antiferromagnetic interactions between the Fe III ions through the oxygen atoms. Evaluated for this first time in catalysis, these compounds showed a high catalytic activity in the oxidation of alkanes and the oxidative formation of benzamides from alcohols.
