Nine azobis(2 pyridine) containing metal complexes:Mn₂(APY)-(Mebix)₂(Ac)₄·4H₂O(1);Cu₂(APY)(Mebix)₂(Ac)₄·4H₂O(2); Ni₂(APY)(Mebix)₂(Ac)₄·4H₂O(3); Cu₂(APY)-(bix)₂(Ac)₄·6H₂O(4); Ni₂(APY)(bix)₂(Ac)₄·6H₂O(5); Mn₂(APY)-(bix)₂(Ac)₄·4H₂O(6); CuGd-(APY)(bix)₂(Ac)₂(NO₃)₃·6H₂O(7); NiGd(APY)(bix)₂(Ac)₂(NO₃) ₃·6H₂O(8); MnGd(APY)-(bix)₂(Ac)₂(NO₃)₃·6H₂O(9) have been prepared and characterized by elemental analysis, infrared, electronic spectra, and ESR.The molecular mechanics and quantum chemical studies have also been engaged to interpret their properties.The cyclic voltammogram studies show that the oxidation reduction processes of (1)~(6) appear to involve an oxidation reduction of APY and two step two electron transfer processes of the bimetallic cores; while the oxidation reduction processes of (7)~(9) involve an oxidation reduction of APY and one step two electron transfer processes of 3d metallic cores.The molecular mechanics and quantum chemical studies demonstrate that there would be a weak antiferromagnetic interaction between the two copper(Ⅱ) units in complex (1), which agrees with the result evaluated by ESR (-2J=11.6 cm^-1).
