摘　　要：A new metal-organic coordination polymer, [Ce（L1）（L2）（H2O）]2H2O （1, H2L1 = 2,6-dimethylpyridine-3,5-diearboxylie acid, H2L2 = （E）-2,6-dimethyl-4-styrylpyridine-3,5-dieerboxylie acid）, has been synthesized and characterized by elemental analysis, IR, and X-ray single-crystal diffraction. Compound 1 crystallizes in trielinic, space group P1 and displays a two-dimensional coordination network structure. In 1, the relatively rare crossed ladders constructed by mixed ligands organize a 2-D grid with the topology of （426）2（48668）, and the layers further build up a 3-D supramoleeular architeetttre via interlaminar hydrogen bonds.A new metal-organic coordination polymer, [Ce（L1）（L2）（H2O）]2H2O （1, H2L1 = 2,6-dimethylpyridine-3,5-diearboxylie acid, H2L2 = （E）-2,6-dimethyl-4-styrylpyridine-3,5-dieerboxylie acid）, has been synthesized and characterized by elemental analysis, IR, and X-ray single-crystal diffraction.
