The syntheses, structures, and magnetic properties are reported of two new high nuclearity Ce–Mn oxo carboxylate clusters at high CeIV/MnIII oxidation states and with nuclearities of Ce5Mn11 and Ce3Mn7. The compounds are (NnBu4)2[Ce5Mn11O13(OH)2(O2CPh)24(NO3)2](NO3) (1) and [Ce3Mn7O8(O2CPh)17(H2O)4] (2). 1 was prepared from the oxidation of Mn(O2CPh)2 by (NnBu4)2Ce(NO3)6, whereas 2 was obtained from...
The title dodecanuclear Mn complex, namely dodeca‐μ2‐acetato‐κ24O:O′‐tetraaquatetra‐μ2‐nitrato‐κ8O:O′‐tetra‐μ4‐oxido‐octa‐μ3‐oxido‐tetramanganese(IV)octamanganese(III) nitromethane tetrasolvate, [Mn12(CH3COO)12(NO3)4O12(H2O)4]·4CH3NO2, was synthesized by the reaction of Mn2+ and Ce4+ sources in nitromethane with an excess of acetic acid. This compound is distinct from the previously known single‐molecule...
