Synthesis and properties of FeIII-N=MnIV heterometallic complex with tetra-tert-butylphthalocyanine ligands

Abstract

Heterometallic N-bridged complex PcFeNMnPc (Pc - tetra-tert-butylphthalocyanine) was synthesized by interaction of PcMnV≡N with PcFeII. As evidenced from UV-vis, IR and EPR data, this complex can be easily oxidized by dioxygen with formation of a stable green cation-radical with one unpaired electron. In protic solvents or in the presence of bases this compound gives blue MnIV=N-FeIII complex with asymmetrical bond distribution in comparison with well known diiron PcFe+3.5NFe+3.5Pc derivatives. © ISUCT Publishing.
