摘要：

A novel 2-D coordination polymer [Mn-2(pdc)(2)(H2O)(3)](n)(.)2n H2O (pdc = pyridine-2,3-dicarboxylate) 1 has been hydrothermally synthesized and characterized by the elemental analyses, IR spectrum, TG analysis along with the single crystal X-ray diffraction. Colorless platelet crystals of compound 1 crystallize in the monoclinic system, space group C2/c, a = 23.900(5) Angstrom, b = 8.581(2) Angstrom, c = 19.833(4) Angstrom, beta = 106.51(3)degrees, V = 3899.8(15) Angstrom(3), Z = 8 and R = 0.0425. The title compound consists of two kinds of Mn-II center with different coordination environments by pdc and water ligands, to form a 2-D sheet, and then constructs a 3-D network by interlayer hydrogen bonds.
