摘　　要：Three new lanthanide complexes with the formulae [Eu2（TsGly）6（phen）2（H2O）2] （1）, [Ln（TsGly）2（phen）2-（H2O）2]C1·2H2O [Ln=Er（2a） and Yb （2b）, TsGly=N-p-tolylsulfonylglycinate, phen= 1,10-phenanthroline] were synthesized. Crystallographic data for 1： monoclinic, P21/n, a= 1.29791（16） nm, b= 1.9034（2） nm, c= 1.7596（2） nm,β=93.410（3）°, V=4.3394（9） nm^3, Z=4, R1 =0.0326, wR2=0.0771; and for 2b： triclinic, P1, a= 1.2674（2） nm, b= 1.4405（2） nm, c= 1.4809（3） nm, a= 113.256（3）°, β= 108.253（3）°, γ=94.739（3）°, V=2.2922（7） nm°3, Z=2, R1=0.0292, wR2=0.0669. X-ray diffractional analysis reveals that compound 1 adopts dinuclear structure with fourfold bridging TsGly ligands between the Eu（Ⅲ） centers, while compound 2b features an unusual mononuclear structure.Three new lanthanide complexes with the formulae [Eu2（TsGly）6（phen）2（H2O）2] （1）, [Ln（TsGly）2（phen）2-（H2O）2]C1·2H2O [Ln=Er（2a） and Yb （2b）, TsGly=N-p-tolylsulfonylglycinate, phen= 1,10-phenanthroline] were synthesized.
