摘要
A new polymer formulated as [Mn3（1,3-BDC）3（L）（H2O）3]（1） based on linear trinuclear unit Mn3（COO）6 has been synthesized under solvothermal conditions with 1,3-benzenedicarboxylic acid（1,3-H2BDC） and 1H-pyrazolo[3,4-b]pyridin-3-amine（L） as ligands. The polymer was characterized by the single-crystal X-ray diffraction analysis, infrared spectra, elemental analyses, power X-ray diffraction and TG analysis. It crystallizes in orthorhombic system, space group Pna21, with a = 7.9252（3）, b = 17.9740（8）, c = 22.3027（10）A°, Mr = 845.35, Z = 4, V = 3177.0（2）A°^3, F（000） = 1708, Dc = 1.767 g/cm^3, μ（Mo Kα） = 1.257 mm^-1, the final refinement give R = 0.0388 and w R = 0.0955 for 5595 reflections with I 〉 2σ（I）. The polymer 1 can be symbolized as a pcu topology based on the Mn3（COO）6 as a secondary building unit. Furthermore, the magnetic properties and electrochemical properties of 1 are also investigated.
