摘要
Lanthanide borohydrides Ln(BH_4)_3(THF)_3 (Ln=Yb, Er), prepared from LnCl_3 and NaBH_4 in THF, were characterized by elemental analysis, infrared spectrum and X-ray diffraction analysis. Yb(BH_4)_3(THF)_3 and Er(BH_4)_3(THF)_3 are isostructural. Each complex contains two η3-BH_4 ligands, an η2-BH_4 ligand and three THF molecules in a distorted octahedron centered about the lanthanide atom. The three B atoms in a complex are coplanar with the lanthanide atom, and the two η3-BH_4 ligands lie opposite to each other.
