Abstract Three new mononuclear cobalt(III) complexes, [Co(L1)2]ClO4·2H2O (1) {HL1 = 2((2(2-hydroxyethylamino)ethylimino)methyl)-6-methoxyphenol}, [Co(L2)(acna)(N3)] (2) {HL2 = 2((2(2-hydroxyethylamino)ethylimino)methyl)-6-ethoxyphenol, Hacna = 2-acetyl-1-naphthol} and [Co(L3)(bzan)(N3)] (3) {HL3 = 1((2(diethylamino)ethylimino)methyl)naphthalen-2-ol, Hbzan = 1-benzoylacetone} were prepared and characterized by elemental and spectral analysis. The structures of all complexes were confirmed by single crystal X-ray analyses. Weak noncovalent interactions lead to the formation of extended supra-molecular assemblies in them. Both complexes 2 and 3 may be used as moderate catalyst for the oxidation of 2-aminophenol to 2-aminophenoxazine-3-one.
