摘　　要：The title compound, [Co（C7N2H7O2）2]n·nH2O 1, was synthesized via the hydrothermal reaction of Co（OAc）2 with 3,5-diaminobenzoic acid and characterized by elemental analysis and infrared spectra. The crystal crystallizes in the monoclinic system, space group P21/c with a = 7.456（3）, b = 9.972（3）, c = 10.391（3）A, β= 106.435（2）°, V = 741.0（4） A^3, Z = 2, C14H16CoN4O5, Mr = 379.24, Dc = 1.700 g/cm^3, F（000） = 390 and μ（MoKa） = 1.194 mm^-l. The final R = 0.0324 and wR = 0.0886 for 1516 observed reflections with I 〉 2σ（I） and R = 0.0337 and wR = 0.0899 for all data. X-ray diffraction studies reveal that the title compound has an interesting 3D microporous architecture with guest water molecules inside the channel. Each Co atom, adopting a distorted octahedral geometry, is coordinated by two O atoms from two 3,5-diaminobenzoate ligands and four N atoms from four symmetry-related 3,5-diaminobenzoate ligands.The title compound, [Co（C7N2H7O2）2]n·nH2O 1, was synthesized via the hydrothermal reaction of Co（OAc）2 with 3,5-diaminobenzoic acid and characterized by elemental analysis and infrared spectra.
