The interaction of alkaline, alkaline earth, transition metals and rare earth elements with alkyl{[benzyl(dialkyl)ammonio]methyl}phosphonates L1 and L2 was studied by Fourier Transform Infrared (FT-IR) spectroscopy. The changes in the nitro group stretching bands, phosphoryl stretching bands were monitored. The main centers of coordination of the ligands have been established.The structure of ethyl{[benzyl(dipropylammonio]methyl}phosphonate characterized by routine X-ray spectroscopy. Single crystal X-ray diffraction analysis showed that the compound crystallizes as a zwitterion in P212121 space group and stabilized by hydrogen O–H•••O bonds.
