摘　　要：Four new rare earth solid complexes with 2,6-pyridinedicarboxylic acid and triphenylphosphine oxide were synthesized for the first time.Their structures and properties have been studied by means of elemental analysis,complexometric titrations,IR,TG-DTA and molar conductivity,and the composition of these complexes can be represented as [RE2(L1)3(L2)(H2O)2]·nH2O(RE=Sm,Eu,Tb,Dy;L1 = 2,6-pyridinedicarboxylic acid;L2 = triphenylphosphine oxide).The fluorescence spectra of them have been determined and they all show the characteristic fluorescent properties of the central ions(Sm3+,Eu 3+,Tb3+,Dy3+).Four new rare earth solid complexes with 2,6-pyridinedicarbexyllc acid and triphenylphosphine oxide were synthesized for the first time. Their structures and properties have been studied by means of elemental analysis, complexometric titrations, IR, TG-DTA and molar conductivity, and the composition of these complexes can be represented as [ RE2 （ L^1 ） 3 （ L^2 ） （ H2 O） 2 ] · nH2O （ RE = Sin, Eu, Tb, Dy; L^1 = 2,6-pyridinedicarboxylic acid ; L2 = triphenylphosphine oxide）. The fluorescence spectra of them have been determined and they all show the characteristic fluorescent properties of the central ions （ Sm^3 ＋ , Eu^3 ＋ , Tb^3 ＋ , Dy^3 ＋ ）.
