Abstract

Quinoline-based, tetradentate nitrogen ligands, N,N′-bis(2-quinolylmethyl)-N,N′-dialkyl-1,2-ethanediamine (alkyl = methyl, bqdmen; ethyl, bqdeen; isopropyl, bqdpen), have been investigated as the supporting ligands for the formation of bis(µ-oxo) dinuclear manganese complexes. Bis(µ-oxo)Mn2(III,III) complexes 1 and 2 were obtained for bqdmen and bqdeen, respectively, as evidenced by X-ray crystallography, whereas bqdpen did not afford any manganese complexes due to its steric bulk. Complexes 1 and 2 exhibit highly positive Mn2(III,III)/Mn2(III,IV) and Mn2(III,IV)/Mn2(IV,IV) redox couples relative to the corresponding pyridine-ligated (µ-O)2Mn2(III,III) complexes.
