摘要：

In this paper we report our recent research on the dinuclear copper(II) and nickel(II) complexes 1-10 (Chart 1) containing Schiff bases, derived from acetylacetone, benzoylacetone, or trifluoroacetylacetone, and 1,3-diaminopropane-2-ol. These complexes are bridged by an alkoxide and a pyridazine (pyd) or phthalazine (phta). The magnetic susceptibilities, visible absorption spectra, conductivities, and redox properties of the complexes were investigated and the molecular structures of 2, 4, and 5 are described. The Cu-O-Cu angles found in these complexes indicate a role of the alkoxo-bridge as one of the principal antiferromagnetic exchange pathways. At the same time, the coplanarity of two coordination planes of copper(II) ions is also shown to relate to the exchange process.
