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/cm3, F(000) = 390 and μ(MoKa) = 1.194 mm-1. 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.
