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).
