摘　　要：A new three-dimensional coordination polymer [Mn（2,3-pdc）（H20）]n （2,3-pdc = pyridine-2,3-dicarboxylate） 1 has been hydrothermally synthesized and structurally characterized. The crystal belongs to the monoclinic system, space group P21/c with a = 6.4168（5）, b = 10.7939（9）, c = 11.1549（10） A, β = 94.733（4）°, V = 769.98（11） A3, Z = 4, Mr = 238.06, De = 2.054 g/cm3, μ（MoKa） = 1.707 mm-1, F（000） = 476, Rint = 0.0326; R = 0.0499 and wR = 0.1636 for 1564 observed reflections with I 〉 2σ（I）. X-ray diffraction analyses reveal that the title compound is a three-dimensional coordination polymer consisting of one MnⅡ center with a distorted octahedral environment arranged by four 2,3-pdc ligands and one water molecule.A new three-dimensional coordination polymer [Mn（2,3-pdc）（H20）]n （2,3-pdc = pyridine-2,3-dicarboxylate） 1 has been hydrothermally synthesized and structurally characterized.
