摘　　要：A 2D coordination polymer, [Co（NPA）（H_2 O）_2]_n（1, H_2 NPA = 3-nitrophthalic acid）, has been synthesized by solvothermal method and characterized by single-crystal X-ray diffraction analysis, FT-IR spectroscopy, elemental analysis, thermogravimetric analysis and powder X-ray diffraction. Complex 1 crystallizes in orthorhombic space group Pbca with a = 7.2261（2）, b = 14.6450（5）, c = 19.6671（7） ？, V = 2081.31（11） ？~3, Z = 8, C_8 H_7 CoNO_8, M_r = 304.08, D_c = 1.941 mg/m^3, μ = 1.686 mm^（-1）, S = 1.054, F（000） = 1224, the final R = 0.0248 and wR = 0.0603 for 1834 observed reflections（I 〉 2σ（I））. The crystal structural analysis demonstrates that the Co（Ⅱ） ions in 1 are linked by single and double μ_2-1,3-bridging carboxylate bridges, forming a 2D layer structure. Moreover, magnetic property of 1 was also discussed.A 2D coordination polymer, [Co（NPA）（H_2 O）_2]_n（1, H_2 NPA = 3-nitrophthalic acid）, has been synthesized by solvothermal method and characterized by single-crystal X-ray diffraction analysis, FT-IR spectroscopy, elemental analysis, thermogravimetric analysis and powder X-ray diffraction.
