By using solvothermal method, two new main group metal coordination polymers based on 2,5-furandicarboxylic acid(H2FDA) ligand, [Sr2(FDA)2(H2O)5]n(1) and [Ba4(FDA)4(H2O)10]n(2), were produced and characterized by single-crystal X-ray diffraction analyses, elemental analyses, IR, and powder X-ray diffraction. Compound 1 crystallizes in monoclinic, space group C2/c with a = 13.454(3), b = 13.426(3), c = 20.166(4), β = 107.06(3)°, V = 3482.4(13) 3, Dc = 2.188 g/cm3, C12H14Sr2O15, Mr = 573.47, F(000) = 2256, μ(Mo Kα)= 6.21 mm–1, Z = 8, R = 0.0522 and w R = 0.1229 for 2493 observed reflections(I > 2σ(I)), and R = 0.0689 and w R = 0.1324 for all data. Compound 2 crystallizes in triclinic, space group P1 with a = 6.8382(14), b = 10.932(2), c = 25.571(5), α = 94.64(3), β = 95.41(3), γ = 107.83(3)o, V = 1799.4(6) 3, Dc = 2.484 g/cm3, C24H28Ba4O30, Mr = 1345.82, F(000) = 1272, μ(Mo Kα) = 4.43 mm–1, Z = 2, R = 0.0485 and w R = 0.0906 for 5020 observed reflections(I > 2σ(I)), and R = 0.0706 and w R = 0.0991 for all data. In 1, the trinuclear clusters Sr3 are connected with adjacent four clusters by a carboxylate group to produce a two-dimensional(2D) sheet, which is extended by a FDA-based pillar into a 3D framework. In 2, neighbouring trinuclear clusters Ba3 are linked through two-O–C–O- of FDA2-ligands to form one-dimensional(1D) chains, which are connected by a FDA-based pillar to construct a 2D framework. The thermal stabilities of 1 and 2 are also investigated.
