摘　　要：A novel lanthanide-organic framework compound [La（seb）（Hseb）（H2O）]n （H2seb = sebacic acid） has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectra, TG and single-crystal X-ray diffraction. Complex 1 crystallizes in the triclinic system, space group P with a = 8.5849（7）, b = 9.0641（8）, c = 15.4049（13）, α = 98.1830（10）, β = 100.6870（10）, γ= 97.5650（10）°, Z = 2, V = 1150.44（17） 3, Dc = 1.612 g/cm3, Mr = 558.39, λ（MoKα） = 0.71073 , μ = 1.903 mm-1, F（000） = 568, R = 0.0219 and wR = 0.0507 for 3797 observed reflections with I 2σ（I）. The structure contains edge-shared chains of [LaO8（H2O）] tricapped trigonal prisms that propagate along the b axis. In aliphatic ligand participation, complex 1 exhibits a three-dimensional supramolecular framework. Moreover, the thermal stability of complex 1 has been investigated.A novel lanthanide-organic framework compound [La（seb）（Hseb）（H2O）]n （H2seb = sebacic acid） has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectra, TG and single-crystal X-ray diffraction.
