| Abstract: | A new one-dimensional chain complex [Co3(Hpda)2(H2O)8] n (I), where HpdaH3 = 4-hydroxypyridine-2,6-dicarboxylic acid, has been synthesized and characterized structurally. It crystallizes in the triclinic space group $Pbar 1$ with a = 7.3718(11), b = 8.4881(13), c = 9.4513(14) Å; α = 110.3300(10)°, β = 100.7470(10)°, γ = 95.338(2)°, V = 536.77(14) Å3, C14H20Co3N2O18, Mr = 681.11, Z = 1, ρc = 2.107 g/cm3, μ = 2.390 mm?1, F(000) = 343, R = 0.0182 and wR = 0.0486 for 1893 observed reflections with I > 2σ(I). Complex I possesses a one-dimensional (1D) chain structure composed of continuous trinuclear Co(II) clusters, which further forms a three-dimensional (3D) supramolecular architecture via hydrogen bonds. |
