摘　　要：Two single crystals [Ln（TBPO）4（NO3）2]NTf2 （Ln = Eu, Gd） were prepared and characterized by element analysis, single crystal X-ray diffraction, PXRD, FT-IR, TGA and fluorescence spectroscopy. The two compounds have similar coordinate structures, in which the central metal ion is coordinated by four TBPO（Tri-n-butylphosphine oxide） molecules and two bidentate nitrates, while NTf2^-（bis（trifluor-（bis（trifluoromethylsulfonyl）imide anion） acts as the counter anion. The packing modes of the two crystals are same. The two single crystals are the focus on 8-coordinate tetra-TRPO complexes（TRPO is Trialkyphosphine oxides）.Two single crystals [Ln（TBPO）4（NO3）2]NTf2 （Ln = Eu, Gd） were prepared and characterized by element analysis, single crystal X-ray diffraction, PXRD, FT-IR, TGA and fluorescence spectroscopy.
