Sažetak
The synthesis, spectroscopic and thermal properties of the novel five-membered N, O metallocyclic complexes of palladium(II) with monoethyl (HL1) and monobutyl (HL2) esters of (alpha-anilino-N-benzyl)phosphonic acid have been reported. The binuclear complexes Pd_2L_4 (L=L1, L2) were obtained by reaction of sodium salts of monoalkyl phosphonates with PdCl_4^2- in aqueous solution. Four organophosphorus ligands bridge two palladium atoms by coordination through the aniline nitrogen and the deprotonated phosphonic acid oxygen. The complexes were identified and characterized by elemental analysis, magnetic and conductance measurements, as well as by the spectroscopic (ESI-MS, IR, UV-Vis, ^1H and ^31P NMR) and thermal (TG, DTA) studies. The properties of the complexes were discussed with respect to those of palladium(II) metallocyclic complexes reported for monoalkyl 4-azobenzene-substituted anilinobenzylphosphonates.
