A 3D coordination polymer [Zn2(hqc)2(H2O)]n has been obtained from the reaction of 4-hydroxyquinoline-2-carboxylic acid (H2hqc) with zinc(II) salt under hydrothermal condition, and characterized by elemental analysis, IR, TGA, PXRD and X-ray single-crystal diffraction. The complex crystallizes in the monoclinic system, space group P21/c with a = 14.305(2), b = 9.132(2), c = 15.356(2), β = 103.586(7)o, V = 1949.9(4)3, Z = 4, Dc = 1.782 g/cm3, μ = 2.508 mm-1, Mr = 523.06, F(000) = 1048, T = 293(2) K, λ(MoKα) = 0.71073, S = 1.008, the final R = 0.0329 and wR = 0.0745 for 3849 observed reflections (I > 2σ(I)). The title complex features a 3D framework via Zn(2) linking the 1D {Zn1(hqc)2}n chains. Thermogravimetric analysis shows that its framework is highly thermally stable up to 556 ℃ in the solid state.
