采用水热方法合成了1个Co（Ⅱ）配合物[Co（p-Cl-C6H4COO）2（phen）（H2O）2].通过单晶X-射线衍射确定了该化合物的分子结构.结构分析表明,该配合物是由分子间氢键将分子连接成一维氢键链,相邻的一维链间通过π-π堆积作用将1D链伸延成2D结构.采用表面光电压光谱（SPS）及场诱导表面光电压光谱（FISPS）技术研究了配合物的表面光伏性能.结果表明配合物在300-600 nm范围内呈现出正的表面光伏响应.同时对该化合物的UV-VIS-NIR和IR光谱进行了测定和分析指认.

A complex [Co（p-Cl-C6H4COO）2 （phen） （H2O）2] has been synthesized by hydrothermal method. The structure of the complex was determined by single crystal X-ray diffraction. The structure analysis shows that the complex is a coordination supramolecule which possesses a 1D chain structure connected by intermolecular hydrogen bonds. The chains are stacked into 2D layer by π-π interaction. The photo-electric property was investigated by surface photovoltage spectroscopy （SPS） and field-induced surface photovoltage spectroscopy（FISPS） techniques. The results indicate that the complex exhibits positive surface photovoltage responses in the range of 300-600 nm. In addition, the UV-VIS-NIR and IR spectra of the complex were measured and analyzed.
