Abstract

A Schiff-base [2+ 2] macrocycle obtained by the reaction of 2, 6-diformyl-4-methylphenol with 1, 11-diamino-3, 9-dimethyl-3, 9-diazo-6-oxaundecane encapsulates three manganese ions into its cavity; EPR, UV–VIS–NIR, XPS spectroscopic data, X-ray crystallography and magnetic measurements showed that the metal ions are in a mixed valence state (II, III, II) which is rare for trimanganese systems.
