摘　　要：A one-dimensional complex,[Gd2(PDC)3(phen)(H2O)·H2O]n(H2PDC=pyridine-3,4-dicarboxylic acid,phen =1,10-phenanthroline),has been synthesized under hydrothermal conditions and characterized by elemental analysis,IR,TG analysis,and X-ray single-crystal structure analysis.Crystallographic data for the title complex: C33H21Gd2N5O14,Mr=1 026.05,Triclinic,space group P,a=0.751 07(15) nm,b=1.256 5(3) nm,c=1.825 7(4) nm,α= 70.80(3)°,β=79.00(3)°,γ=76.05(3)°,V=1.567 4(5) nm3,the final refinement gave R=0.022 4 and wR=0.047 5 for 4 913 observed reflections with I>2σ(I).The coordination polymer displays a 1D belt-like chain.The 1D chain connected with adjacent chains through π-π stacking interaction of phen groups to form 2D layers,which are further extended to a 3D supramolecular network through H-bonds interaction.CCDC: 671430.A one-dimensional complex, [Gd2（PDC）3（phen）（H2O）· H2O]n （H2PDC=pyridine-3,4-dicarboxylie acid, phen =l,10-phenanthroline）, has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, TG analysis, and X-ray single-crystal structure analysis. Crystallographic data for the title complex： C33H21Gd2N5O14, Mr=1 026.05, Triclinic, space group P1, a=0.751 07（15） nm, b=1.256 5（3） nm, c=1.825 7（4） nm, α= 70.80（3）°, β=79.00（3）°, γ=76.05（3）°, V=1.567 4（5） nm^3, the final refinement gave R=0.022 4 and wR =0.047 5 for 4 913 observed reflections with I〉2σ（I）. The coordination polymer displays a 1D belt-like chain. The 1D chain connected with adjacent chains through π-π stacking interaction of phen groups to form 2D layers, which are further extended to a 3D supramolecular network through H-bonds interaction.
