Infrared spectra of monoalkyl (alpha-anilino-N-benzyl)phosphonates, their sodium salts and dipalladium(II) metallocyclic complexes
Infrared spectra of monoethyl (HL1) and monobutyl (HL2) esters of (alpha-anilino-N-benzyl)phosphonic acid, their sodium salts (NaL1 and NaL2) and dipalladium(II) complexes (Pd_2L_4, L=L1, L2), have been studied. Monoalkyl esters were found to have zwitterion structure. Their binuclear [N, O] metallocyclic complexes possess four organophosphorus ligands bridged by two palladium atoms through the aniline nitrogen and the deprotonated phosphonic acid oxygen. The spectral results obtained were discussed with respect to those of the corresponding 4-azobenzene-substituted anilinobenzylphosphonate derivatives.
