SYNTHESES AND INFRARED SPECTRA OF RARE EARTH COMPLEXES WITH DIMETHYL PHOSPHATE
Abstract:
The solid complexes of Sm, Eu, Ho, Yb and Lu with dimethyl phosphate (DMP) were synthesized by reaction of trimethyl phosphate(TMP) with corresponding rare earth chlorides. The mechanism of thermodecomposition of the complexes has been studied. Their infrared spectra were measured and main infrared absorption bands were assigned. The result showed that the polymeric title complexes are extremely similar to Sm(DMP)3 single crystal in the spectral properties of RE-O bond and PO2 group. Thus these complexes may have the same molecular configuration, i.e. dimetbyl phosphate anions coordinate with lanthanide atoms through double O-P-O bridges to form a special network of rings-linking-rings, each of which consists of twenty-four atoms. The RE-O bond of RE(DMP)3 is principally ionic.
