摘　　要：采用水热和常规方法合成了2种Ni的配合物[Ni(phen)2(C6H5COO)].(NO3).2(C6H5COOH)(1)和[Ni(H2O)6].2HSO4.C2H8N2(2).通过X射线单晶衍射、红外光谱(IR)、紫外可见吸收光谱(UV-Vis)及表面光电压光谱(SPS)等方法对配合物进行了表征.结果表明:配合物(1)、(2)在分子内和分子之间存在大量氢键,使其连接成具有3D网络结构的配位超分子.重点研究了配合物的SPS光谱,并与其相应的UV-Vis吸收光谱进行了对照,两者呈现了较好的对应关系.Under hydrothermal conditions,two complexes [Ni（phen）2（C6H5COOH）]·（NO3）·2（C6H5COOH）（1）and [Ni（H2O）6]·2HSO4·en（2）were synthesized.The crystal structures of two complexes were determined by X-ray single crystal diffraction,and the two complexes were characterized by IR,UV-Vis-NIR and Surface Photovoltage Spectroscopy（SPS）.The results indicate that many kinds of hydrogen bonds make two complexes further be connected to 3D network structure,forming supramolecules.Surface photovoltage performance of two complexes were emphatically studied.By contrasting SPS with UV-Vis-NIR spectra,it is found that these response bands in SPS are consistent with Absorption peaks in the UV-Vis-NIR spectra.
