Heptanuclear metal‐centered, six‐membered, mixed‐valent, heterometallic wheels 1 – 3 of iron, manganese, and indium were prepared in a one‐pot reaction from N ‐benzyldiethanolamine (H 2 L 1 ), cesium carbonate, [PPh 4 ] 2 [MnCl 4 ], and FeCl 3 or InCl 3 . All three complexes were characterized by the combination of elemental analysis, FAB mass spectroscopy, X‐ray diffraction and cyclic voltammetry. and in the case of 1 additionally by Mössbauer spectroscopy. In 1 , four Mn II ions in the periphery are arranged in pairs alternating with one Fe III ion each, with an Fe III ion located in the center. In 2 , three Mn II ions alternate with three In III ions, whereas in 3 , four In III ions are arranged in pairs and alternate with one Mn II ion each. In 2 and 3 an Mn II ion is encapsulated in the center.
