Resumo
A series of Cu, Ni, and Mn complexes based on formylpyrone and formylcoumarin azomethynes with 1,3- diaminepropanol-2. The analysis of XANES and EXAFS spectra of the Cu, Ni, and Mn complexes, which were processed by both Fourier and wavelet transforms, enables the determination of local atomic structural parameters and the unambiguous evidence of the formation of both dinuclear and mononuclear structures of these coordination compounds. The possibility of forming binuclear compounds is shown to depend mainly on the nature of the bridging ligand and be independent of the type of the polydentate azomethyne ligand: pyrone or coumarin. The obtained structural results are well consistent with the magnetochemical data for the complexes.
