INFRARED SPECTRA OF RARE EARTH COMPLEXES OF 2-ETHYLHEXYL PHOSPHONIC ACID MONO(2-ETHYLHEXYL)ESTER
Abstract:
The solid complexes of La, Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho, Er,Tm, Yb, Lu, and Y with 2-ethylhexyl phosphonic acid mono(2-ethylhexyl)ester were prepared.FTIR spectra of these complexes have been studied and the principal infrared absorption bands have been assigned for region 4000-100cm-1.The 150cm-1 is believed to be Ln-O stretching vibration band, and the band near 250cm-1 is the coupling band of COPO, CCPO skeleton torsion vibration with Ln-O bond. The experimental result showed that Ln-O bonds in these rare earth complexes are principally ionic.,The FO2 coordination with rare carth is in bridging form. A Volymeric model of the complexes is proposed(Fig. la)
