系列咪唑-M（M=Ni^2＋，Cu^2＋，Co^2＋）配位超分子的晶体结构及光物理性能

采用水热方法合成了咪唑-M配位化合物Ni（imH）6]·（NO3）2（1）；Cu（imH）6]·（C7H602）2（2）；Co（imH）6]·（NO3）2（3）．对3种配合物的单晶进行了X-射线单晶衍射分析，结果表明3个配合物的内界相同，都是由6个咪唑分子分别用1个N原子与金属离子配位，形成了6配位的畸变八面体构型．其中配合物（1）和（3）的外界含有2个硝酸根离子，属于同构结构．配合物（2）的外界包含2个苯甲酸根离子．分子中存在的大量氢键将3个配合物分别连接成2D，3D和2D氢键网络结构．对配合物进行了IR光谱和UV—Vis-NIR光谱的表征．

Crystal structures and photo-physical property of a series of imH-M coordination supramolecule(M = Ni2 +, Cu2 +, Co2 + ; imH = imidazole)

A series of complexesNi（imH）6]·（NO3）2（1）;Cu（imH）6]·（C7H602）2（2）;Co（imH）6]·（NO3）2（3） were synthesized under hydrothermal condition. The crystal structures of the complexes were determined by the single-crystal X-ray diffraction. The results show that these three comlpexes are uniform interior which form a slightly distorted octahedron . Six nitrogen atoms from six imidazole molecules coordinate with relevant metal ion. There are two NO3^- ions in the exterior of complexes （1） and （3）. They are structural isomorphism. There are two benzoic acid groups in the exterior of （2）. These complexes respectively possess 2D, 3D and 2D infinite network structure by many kinds of hydrogen bonds, forming supramolecules. In addition, the IR,UV-VIS-NIR spectra were measured and analyzed.
