采用水热方法合成了1个新的Cu（Ⅱ）配合物[Cu（pdc）2]·[（CH3）2 NH2]2（H2 pdc＝吡啶-2，5-二羧酸）．通过X射线单晶衍射确定了该配合物的结构．对配合物进行了IR、固体UV-Vis 吸收光谱、表面光电压光谱（SPS ）和场诱导表面光电压光谱（FISPS ）、热重等物性表征．结构分析表明，该配合物为 Cu （Ⅱ）的单核配合物，其中Cu（Ⅱ）离子为四配位（CuN2 O2配位模式），形成扭曲的平面四边形构型．晶体中，分子间通过Cu…O弱键及氢键网联成3D超分子．SPS结果表明，该配合物在300～800 nm范围内呈现出一定的光电响应，表明它具有一定的光电转换能力．将SPS与UV-Vis光谱进行了关联，发现它们具有密切关系．

A complex [Cu(pdc)2]· [(CH3)2NH2]2 has been synthesized by hydrothermal method .Its structure was determined by single crystal X ray diffraction .The complex was characterized by infra-red spectrum (IR) ,solid phase ultraviolet-visible absorptiom spectra (UV-Vis) ,thermogravimetric a-nalysis ,surface photovoltage spectroscopy (SPS) and field-induced surface photovoltage spectroscopy (FISPS) .The structural analysis shows that the complex is a mononuclear Cu (Ⅱ) complex ,in which the Cu(Ⅱ ) ion is four-coordinated with a distorted square-planar configuration .In crystal of the complex ,the complex was networked into a 3D supramolecule by Cu … O weak bond and hydrogen bonding .The SPS results show that the complex exhibits obvious surface photovoltage responses in the range of 300~800nm ,w hich indicates that it possess certain photo-electric conversion properties . The SPS results are interrelated with the results of UV-Vis spectrum ,they exhibit a close relation-ship .
