A set of porphyrinoid manganese(IV) complexes with the 2,3,7,8,12,13,17,18‐octaethyl‐5,15‐di‐ p ‐tolylcorrolato ligand [(oedtc)Mn IV X] (X = Cl, Br, I) was prepared by oxidation of a manganese(III) precursor. The most unexpected complex in this series, [(oedtc)Mn IV I], was found to display significant thermal stability despite the unusual Mn IV ‐I bond and could be investigated by X‐ray diffraction. Attempted ligand exchange reactions of the chlorido derivative with the pseudohalide anions cyanide, azide, cyanate and thiocyanate yielded the desired [(oedtc)Mn IV X] complex only as the isothiocyanate derivative while for the other species the reduction to manganese(III) was observed.
