摘　　要：羧酸配合物具有丰富的拓扑结构。在磁学、光学、催化、生物等诸多领域有广泛的应用前景，人们对羧酸配合物的研究一直保持着浓厚的兴趣。近年来，我们也合成了一些新的羧酸配位聚合物，并对其性质进行了分析．我们使用较多的配体主要是芳香羧酸、柔性羧酸及杂环饱和羧酸，而以杂环不饱和羧酸和邻菲咯啉为配体的镉配位聚合物报道相对较少。One-dimension chain coordination polymer [Cd（phen）（α-Furacrylic acid）2]n has been synthesized by means of hydrothermal synthesis with α-Furacrylie acid and 1,10-phenan throline （phen）. It crystallizes in the Orthorhombic space group Pbcn, with a=2.524 9（5） nm, b=1.106 5（2 ）nm, c=0.786 86（16） nm, V=2.198 2（8） nm^3, De= 1.713 g·cm^-3, Z=4, F（000）= 1 136. Final GooF= 1.245, R 1=0.046 1, wR2=0.117 3. The crystal structure shows that the cadmium ion is coordinated with six oxygen atoms from four α-Furacrylic acid group, two nitrogen atoms from the 1,10-phenanthroline, respectively, forming a distorted square antiprism coordination geometry. One oxygen atom of the carboxyl of the α-Furacrylic acid group coordinated to the two cadmium（R） ions with the bridge coordination mode, and the other oxygen atoms of the carboxyl of the α-Furacrylic acid group coordinated to the one cadmium（Ⅱ） ion resulting in the bisdentate chelated coordination mode. The two oxygen atoms that with bisdentate chelated coordination mode and the two cadmium （Ⅱ） ions from a parallelogram geometry. The luminescence property of the complex is also studied.
