以咪唑为配体的钴和镍的配合物的合成、晶体结构及电化学性质(英文)

Syntheses,Crystal Structures and Electrochemical Properties of Cobalt and Nickel Complexes Containing Imidazole Ligand

合成了2种新颖的配合物[M(ImH)6](tfbdc)(M=Co,Ni;tfbdc=2,3,5,6-四氟对二苯甲酸根;ImH=咪唑),并通过元素分析,红外光谱,热重分析,循环伏安及X-射线单晶结构分析对其结构及性质进行了表征。2个配合物[Co(ImH)6](tfbdc)(1)和[Ni(ImH)6](tfbdc)(2)都属单斜晶系,空间群为P21/c,且Z=2。每1个金属离子与来自6个咪唑分子的6个氮原子配位,形成八面体配位构型。独立组分,[M(ImH)6]2+阳离子和四氟对二苯甲酸阴离子之间通过两种氢键(N-H…O和C-H…F)连接形成了一种三维的超分子网络结构。

Two novel complexes [M（ImH）6]（tfbdc）（M=Co,Ni;ImH=imidazole,tfbdc=2,3,5,6-tetrafluoroterephthalate） were synthesized and characterized by elemental analysis,IR spectra,thermogravimetric analysis,cyclic voltammetry,and X-ray single crystal structure analysis.Both [Co（ImH）6]（tfbdc）（1） and [Ni（ImH）6]（tfbdc）（2） all crystallize in the monoclinic system,space group P21/c,and with Z=2.Metal ions have all octahedral geometry coordinated by six N atoms from six imidazole molecules.The independent components,[M（ImH）6]2＋ cations and tfbdc anions are connected into a three-dimensional supramolecular network by N-H…O and C-H…F hydrogen bonds.
