采用水热合成法，以2，5-吡啶-二羧酸为配体，得到了Cd（Ⅱ）配聚物：[Cd2（2，5-pdc）2（H2 O ）4]n （2，5-H2 pdc＝2，5-吡啶-二羧酸）。采用X射线单晶衍射确定了配聚物的晶体结构。配聚物的不对称单元为 Cd2（2，5-pdc）2（H2 O）4，其中两个不等效的金属Cd（Ⅱ）离子均为6配位。在配聚物晶体中，Cd（Ⅱ）离子之间通过pdc2-上的羧基O原子连接，形成了具有2D结构的配聚物，氢键进一步将其连接成3D超分子。采用表面光电压光谱（S PS ）研究了配聚物的表面光电性能。结果表明，该配聚物在300～800 nm范围内呈现出较强的光伏响应，表明他具有一定的光-电转换能力。对配聚物的 U V-Vis-NIR吸收光谱、IR光谱进行了测定和指认，并将 SPS 谱与 UV-Vis-NIR 吸收光谱进行了关联。

The polymer [Cd2 (2 ,5-pdc)2 (H2 O)4 ]n has been synthesized by hydrothermal method with the 2 ,5-H2 pdc as ligand .The crystal structure of the polymer was determined by single crystal X ray diffraction .Structural analysis shows that the asymmetric unit is Cd2(2 ,5-pdc)2(H2O)4 ,in which the two independent Cd(Ⅱ )ions(Cd1 and Cd2)are all six-coordinated .In the crystal ,Cd(Ⅱ )ions are bridged by the O atoms of pdc2 - groups into 2D extended structure .Moreover ,the intermolecular H-bonds connect 2D layers into 3D structure .The photo-electric property of the polymer was investiga-ted by surface photovoltage spectroscopy (SPS) .The result indicates that the polymer exhibits posi-tive surface photovoltage responses in the range of 300~800 nm ,so it possesses certain photo-electric conversion property .The UV-Vis-NIR and IR spectra of the polymer were measured and analyzed . And the SPS spectrum has been related with its UV-Vis-NIR spectrum .
