利用四氟苯甲酸(H2tfbdc),1,10-邻菲咯啉与四水醋酸钴在甲醇和水混合溶剂中的反应,得到了标题配合物[Co(O2CC6HF4)2(Phen)2]。用元素分析、红外光谱、热重分析、循环伏安、X-衍射单晶结构分析等对其进行了表征。晶体结构表明,标题配合物的晶体属单斜晶系,空间群为P21/c,晶胞参数:a=1.3719(8)nm,b=1.5956(10)nm,c=1.5849(10)nm,β=106.327(10)°;每个钴离子与来自2个2,3,5,6-四氟苯甲酸分子的2个氧原子和2个1,10-邻菲咯啉分子的4个氮原子配位,形成变形的八面体配位构型。[Co(O2CC6HF4)2(Phen)2]独立结构单元通过两种氢键(C-H…F和C-H…O)形成三维的超分子网络结构。
The title complex [Co (O2CC6HF4) 2 (Phen) 2] was obtained by the reaction of tetrafluorobenzoic acid (H2tfbdc), 1,10-phenanthroline and cobalt acetate tetrahydrate in a mixed solvent of methanol and water. It was characterized by elemental analysis, infrared spectroscopy, thermogravimetry, cyclic voltammetry and X-ray diffraction. The crystal structure of the title complex shows that the crystal of the title complex is monoclinic with the space group of P21 / c and unit cell parameters of a = 1.3719 (8) nm, b = 1.5956 (10) nm and c = 1.5849 β = 106.327 (10) °; each of the cobalt ions interacts with four nitrogen atoms from two oxygen atoms of two 2,3,5,6-tetrafluorobenzoic acid molecules and two molecules of 1,10-phenanthroline The atoms coordinate to form a deformed octahedral coordination configuration. The [Co (O2CC6HF4) 2 (Phen) 2] independent structural unit forms a three-dimensional supramolecular network structure by two hydrogen bonds (C-H ... F and C-H ... O).
