Four types of novel manganese complexes, MnIV (N-EtO-sal)2, MnIII(N-PhO-sal)(L), [MnIV(5,6-Benzo-L)2 (μ-O)2]2, and MnIII(L-4-Me)3 have been found to be obtained by the reactions of KMnO4 with tridentate Schiff base ligands (N-EtOH-salH, N-PhOH-salH and their derivatives) in dry MeCN, where N-EtOH-salH, N-PhOH-salH, LH, 5,6-Benzo-LH, and L-4-MeH denote N-2-hydroxyethyl-salicylideneamine, N-2-hydroxyphenyl-salicylideneamine, 2-(2-hydroxyphenyl)-benzoxazole, 2-(2-hydroxynaphthyl)-benzoxazole, and 2-(2-hydroxyphenyl)-5-methylbenzoxazole, respectively.
