The new complexes of Cu(II) and Pd(II) with Schiff  bases on base of 4-aminoantipyrine and salicylaldehyde derivatives were obtained. Using of IR, electronic absorption spectrophotometry, thermogravimetry and other methods the structure of these complexes has been investigated. At complex formation the hydrogenated on azomethine group schiff bases undergo to oxidative dehydrogenation with corresponding Schiff bases. It is shown, that for Pd(II) it is possible to obtain the complexes with hydrogenated ligands
