      abstract     = {New heterometallic In–Fe alkoxides [InFe(OtBu)4(PyTFP)2]
                      (1), [InFe2(OneoPen)9(Py)] (2), and [InFe3(OneoPen)12] (3)
                      were synthesized and structurally characterized. The
                      arrangement of metal centers in mixed-metal framework was
                      governed by the In:Fe ratio and the coordination preferences
                      of Fe(III) and In(III) centers to be in tetrahedral and
                      octahedral environments, respectively. 3 displayed a
                      star-shaped so-called “Mitsubishi” motif with the
                      central In atom coordinated with three tetrahedral
                      {Fe(OneoPen)4}− anionic units. The deterministic
                      structural influence of the larger In atom was evident in 1
                      and 2 which displayed the coordination of neutral coligands
                      to achieve the desired coordination number. Thermal
                      decomposition studies of compounds 1–3 under inert
                      conditions with subsequent powder diffraction studies
                      revealed the formation of Fe2O3 and In2O3 in the case of 3
                      and 2, whereas 1 intriguingly produced elemental In and Fe.
                      In contrary, the thermal decomposition of 1–3 under
                      ambient conditions produced a ternary oxide, InFeO3, with
                      additional Fe2O3 present as a secondary phase in a different
                      stoichiometric ratio predetermined through the In:Fe ratio
                      in 2 and 3. The intimate mixing of different phases in
                      InFeO3/Fe2O3 nanocomposites was confirmed by transmission
                      electron microscopy of solid residues obtained after the
                      decomposition of 1 and 2. The pure InFeO3 particles
                      demonstrated ferromagnetic anomalies around 170 K as
                      determined by temperature-dependent field-cooled and
                      zero-field-cooled magnetization experiments. A first-order
                      magnetic transition with an increase in the ZFC measurements
                      was explained by temperature-induced reduction of the
                      Fe–Fe distance and the corresponding increase in
                      superexchange.},
