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; tfbdc = 2,3,5,6-tetrafluorodibenzoate; ImH = imidazole) were synthesized and purified by Its structure and properties were characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis, cyclic voltammetry and X-ray single crystal structure analysis. The two complexes [Co (ImH) 6] (tfbdc) (1) and [Ni (ImH) 6] (tfbdc) (2) are monoclinic with a space group of P21 / c and Z = 2. Each metal ion coordinates with six nitrogen atoms from six imidazole molecules to form an octahedral coordination configuration. The independent component, [M (ImH) 6] 2+ cation and tetrafluorobiphenyl anion are connected by two kinds of hydrogen bonds (N-H ... O and C-H ... F) to form a three-dimensional supramolecular network structure.
