FIELD: chemistry.SUBSTANCE: invention relates to methods of obtaining novel compounds of divalent lanthanides Ln(II), namely to method of obtaining compounds LnCl·0.5HO·(0.04-0.07)Bu?AlO. Method of obtaining compounds of lanthanides LnCl·0.5HO·(0.04-0.07)Bu?AlO, where Ln=Sm or Ln=Yb lies in reduction of trivalent lanthanides Ln(III), with crystallohydrates YbCl·6HO and SmCb·6HO being used as such, to divalent lanthanides Ln(II), on condition that molar ratio LnCl·6HO/Bu?Al constitutes 1/50-70, and reaction takes place at atmospheric pressure, room temperature, in hexane, in nitrogen atmosphere.EFFECT: invention makes it possible to obtain novel compounds of divalent lanthanides and ensures ecological safety of their obtaining.1 tbl, 1 ex |
