Abstract: The dipyridine (dipy) complexes of rare earth(Ⅲ) B20H18 were prepared throughfollowing reactions: 3H2B20H18+Ln2O3→Ln2(B20H18)3 +3H2O Ln2(B20 H183 + 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 non-polar solvents. They are stable to air and moisture.The complexes were identified by elemental analysis, electroconductivity, IR spectraand 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.
