摘　　要：A novel coordination polymer [Na2Pd（2,6-pydc）2（H2O）6]n （2,6-H2pydc = 2,6-pyridinedicarboxylic acid） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to the monoclirtic system, space group P21/c, with a = 11.962（2）, b = 6.5552（13）, c = 12.673（3） A, β = 91.72（3）^o, V = 993.3（3） A^3, Z = 2, Mr = 590.68, Dc = 1.975 g/cm^3,μ = 1.059 mm^-1, F（000） = 592, the final R = 0.0211 and wR = 0.0454. In the crystal the Pd（II） ion adopts a distorted four-coordinated square-planar geometry and bonds to two bidentate 2,6-pyridinedicarboxylate molecules through caronyl oxygen and pyridine nitrogen atoms. The title complex exhibits a novel three-dimensional network structure.A novel coordination polymer [Na2Pd（2,6-pydc）2（H2O）6]n （2,6-H2pydc = 2,6-pyridinedicarboxylic acid） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction.
