Abstract

Abstract: In the presence of structure‐directing isobutyrate (ib) ligands, Ce III and Mn II salts undergo a sequence of oxidation and condensation steps, which result in the intermittent formation of the neutral coordination cluster [Mn10 O2 (ib)18 (Hib)2 ], followed by Mn‐decorated {Ce10 Mn8 } clusters. Their common inorganic {Ce IV 10 Mn II 2 Mn III 6 O18 } core features a cerium oxide substructure with a decavanadate‐type metal framework, which showcases that molecular cerium oxide structures indeed can adopt certain structural principles of classical polyoxometalates. In addition, we identified the exact composition and structure of the precursor "manganese isobutyrate", which actually consists of [Mn6 (ib)12 (Hib)6 ] macrocycles. Abstract : Controlled condensation and oxidation of manganese(II) and cerium(III) precursors in the presence of structure‐directing ligands result in a sequence of coordination clusters with increasing oxide/metal ratio, which leads to a Mn‐decorated decavanadate‐type cerium(IV) oxide framework.
