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.
