ABSTRACT

Azomethine HL was synthesized by the reaction of o-aminophenol with 2-acetylbenzimidazole and used to prepare the cobalt(III) complex [CoL2]2(ClO4)2⋅3H2O (I). The structure of complex I was established by NMR spectroscopy in solution and by single crystal X-ray diffraction (CIF file CCDC no. 2051279). The cobalt ion in the +3 oxidation state has an octahedral environment. The crystals are monoclinic, space group C2/c, a = 12.405(7), b = 13.946(11), c = 18.907(13) Å, α = 109.87(3)°, β = 94.534(12)°, γ = 104.564(19)°, V = 2928(3) Å3, ρ(calcd.) = 1.521 g/cm 3, Z = 2. The complex is diamagnetic. Study of the electrochemical behavior of I in acetonitrile showed that it can be reduced to neutral and radical anion forms. More... »
