A novel coordination polymer [Na2Pd(2,6-pydc)2(H2O)6]n (2,6-H2pydc = 2,6-pyri- dinedicarboxylic acid) has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c, with a = 11.962(2), b = 6.5552(13), c = 12.673(3) , β = 91.72(3)°, V = 993.3(3) 3, Z = 2, Mr = 590.68, Dc = 1.975 g/cm3, 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.
