Abstract

The approach based on isomorphous substitution permitted preparation of (Co, Ni)4(acac)4(μ3–OMe)4(MeOH)4(I) via interaction of individual M4(acac)4(μ3–OMe)4(MeOH)4 in toluene/methanol media. The oxidation of I in air in solution in MeOH in the presence of NaOAc and aminoalcohols as catalysts gives Co2Ni2-(acac)4(μ3–OMe)4(OAc)2(II). The symmetrization reaction between a complex formed by a hard Pearson acid and a soft Pearson base and that formed by a soft acid and a hard base led to CuNi2(OCOC2H5)3(ORN)3-(RNOH)(III) and Ni(Ni0.25Cu0.75)2(μ3–OH)(μ2–OAc)(OAc)2(μ2, η2-ORN)3(η2-RNOH)(IV) RN = CH(CH3)-CH2NMe2 via interaction of Ni(ORN)2 with copper propionate and copper acetate hydrate respectively in hydrocarbon media.
