STUDIES ON BORANE COMPOUNDS ⅩⅩⅧ. SYNTHESIS AND CHARACTERIZATION OF DIPYRIDINE COMPLEXES OF RARE EARTH METAL(Ⅲ)B20H18
Abstract:
The dipyridine (dipy) complexes of rare earth(Ⅲ)B20H18 were prepared throughfollowing reactions: 3H2B20H18+Ln2O3→Ln2(B20H18)3+3H2O, Ln2(B20H18)3+8dipy
[Ln(dipy)4]2(B20H18)3 where Ln=Yb, Tm, Ho, Gd and Sm.All the compounds obtained are solid and soluble in polar solvents, but not in nonpolar solvents. They are stable to air and moisture.The complexes were identified by elemental analysis, electroconductivity, IR spectra and TG-DTA measurements. Dipy is found to be Londed to the rare earth via N atom.The molar conductance data indicate that these complexes are ionic and behave as 2:3 electrolytes in DMF.
