Mn(iv) and Mn(v)-radical species supported by the redox non-innocent bis(2-amino-3,5-di-tert-butylphenyl)amine pincer ligand†
Abstract
The electron-rich pincer ligand 1 has been synthesized and chelated to manganese. The octahedral Mn(IV) bis(diiminosemiquinonate) and Mn(V) (diiminobenzoquinone) (diiminosemiquinonate) radicals were structurally characterized.
