| Abstract: Two lanthanide coordination polymers [Gd(L)3H2O]n(1) and [Nd(L)3H2O]n(2) were hydrothermally synthesized by reaction of flexible nitrogen-containing carboxylate ligand 2-(1H-1,2,4-triazol-1-yl)acetic acid (HL) with lanthanide oxides and characterized by elemental analysis, IR and single crystal X-ray diffraction structure analysis. The crystal structures showed that two complexes belong to triclinic, space group P1 with 1D chain structure. The crystallographic data of complex 1: a=0.882 41(13) nm, b=0.986 58(14) nm, c=1.100 81(16) nm, α=81.352(2)°, β=87.168(2)°, γ=76.563(2)°, Z=2, R=0.035 8, wR2=0.065 3; the crystallographic data of complex 2: a=0.882 41(13) nm, b=0.986 58(14) nm, c=1.100 81(16) nm, α=81.352(2)°, β=87.168(2)°, γ=76.563(2)°, Z=2, R=0.026 8, wR2=0.060 2.
