A new polymer formulated as [Mn-3(1,3-BDC)(3)(L)(H2O)(3)] (1) based on linear trinuclear unit Mn-3(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 Pna2(1), with a = 7.9252(3), b = 17.9740(8), c = 22.3027(10) angstrom, M-r = 845.35, Z = 4, V = 3177.0(2) angstrom(3), F(000) = 1708, D-c = 1.767 g/cm(3), mu(MoKa) = 1.257 mm(-1), the final refinement give R = 0.0388 and wR = 0.0955 for 5595 reflections with I > 2 sigma(I). The polymer 1 can be symbolized as a pcu topology based on the Mn-3(COO)(6) as a secondary building unit. Furthermore, the magnetic properties and electrochemical properties of 1 are also investigated.
