【Abstract】 Complexes of cerium group elements with di ( 1-methylheptyl) phosphoric acid have been prepared and studied through elemental analysis and i. r. spectra. The results obtained indicate that all the complexes correspond to the general formula LnL3 ( where Ln = La, Ce, Pr, Nd, Sm; HL= [C6H13CH(CH3 ) O ] 2 P (O)OH) and the coordination between rare earth ion and ligand occurs through the two oxygen atoms of ■ in the ligand,with coordination number six.More- over, thermal decomposition of these complexes has also been investigated.更多还原
