A new coordination polymer, namely [Ca(HOABDC)]n(1, H3 OABDC = 5-oxyacetateisophthalic acid), has been synthesized through hydrothermal reactions of Ca(NO3)2 and H3 OABDC. The title compound crystallizes in monoclinic, space group P21/c with a = 4.3043(2), b = 21.4959(11), c = 10.7450(6) A, β = 91.411(5)o, V = 993.88(9)A3, C10H6O7 Ca, Mr = 278.23, Z = 4, Dc = 1.859 g/cm3, F(000) = 560, μ = 0.659 mm-1, the final R = 0.0328 and wR = 0.0670 for 1469 observed reflections(I > 2A(I)). Single-crystal X-ray structural analysis reveals that compound 1 features 1D Ca(Ⅱ)-carboxylate chain-shaped subunits, which are further connected together via HOABDC2- ligands into a 3D(6,6)-connected nia-type hybrid framework. Moreover, the luminescent property and thermal stability of 1 were also investigated.
