STUDIES ON COMPLEXES OF RARE EARTHS WITH CROWN ETHERS(Ⅳ)SYNTHESIS AND CHARACTERIZATION OF THE COMPLEXES OF RARE EARTH NITRATES WITH 4'-BROMO-5'-NITROBENZO-15-CROWN-5
摘要:
Six new solid complexes of macrocyclic polyether ligand 4'-bromo-5'-nitrobenzo-15-crown-5（L）with trivalent rare earth nitrates having composition of RE（NO3）3·L·mCH3CN·nH2O（RE=La--Nd, m=n=0, RE=Sm, Bu, m=0, 1, n=1, 4）have been synthesized in acetonitrile or acetone.All the isolated complexes have been characterized by elementary analysis, IR and UV spectra, differential thermal and thermogravimetric analysis, X-ray powder diffraction analysis, molar conductance and measurementa of solubility in some general solventa.It shows that coordination number of the rare earth cation in the complexes of La, Ce, Pr and Nd nitrate is eleven.
