Abstract

Bis(diphenylphosphorylmethyl) ethers of oligo(ethylene glycols) Ph2P(O)CH2O(CH2CH2O) n CH2P(O)Ph2 (Ln, where n = 1-3) and coordination compounds of Nd and Er with L3 are synthesized. The dependence of extractability of L1-3 on the structure of complexes in the 1,1,7-trihydrododecafluoroheptanol–water system at a concentration of HNO3 0.5-6.0 mol/L is determined. The crystal structure of [NdL3(NO3)3(H2O)] is studied by X-ray diffraction.
