摘　　要：以市售的三联苯六羧酸为功能配体,采用溶剂热合成技术,辅以常温挥发法构筑了一例结构独特的钴(Ⅱ)配合物晶体,采用X-射线单晶衍射仪对该晶体的结构进行表征和分析。结果表明,该晶体属于单斜晶系,C12/c1空间群,晶胞参数为a=18.4761(14)Å,b=8.7895(6)Å,c=23.4547(17)Å,α=90.00°,β=100.6500(10)°,γ=90.00°,V=3743.3(5)Å3,Z=4,F(000)=1464,μ=0.942 mm^(-1)。中心金属钴(Ⅱ)原子分别与三联苯六羧酸配体的羧基官能团的5个氧原子(O2、O3、O4、O5、O7)和1个水分子的氧原子(O1)配位形成扭曲的八面体构型,且O2、O3、O4、O7具有一定的共面性。借助中心金属钴(Ⅱ)原子与配体和桥联水分子的氧原子的配位,而沿z轴方向无限延展,形成具有蜂窝状的三维多孔网状结构。该配合物的合成有望为纺织印染废水的吸附处理提供一种潜在的功能材料。A novel cobalt(Ⅱ)complex with unique structure is constructed by solvothermal synthesis and normal temperature volatilization using commercially available triphenyl hexarboxylic acid as functional ligand,and then characterized by X-ray single crystal diffractometer.The results show that the crystal belongs to monoclinic system,C12/c1 space group.The crystal cell parameters for a=18.4761(14)Å,b=8.7895(6)Å,c=23.4547(17)Å,α=90.00°,β=100.6500(10)°,γ=90.00°,V=3743.3(5)Å3,Z=4,F(000)=1464,μ=0.942 mm^(-1),respectively.The central metal cobalt(Ⅱ)atom coordinates with five oxygen atoms(O2,O3,O4,O5,O7)of the carboxyl functional group of the triphenylhexacarboxylic acid ligand and the oxygen atom(O1)of one water molecule to form a twisted octahedral configuration,and O2,O3,O4 and O7 have certain coplanarity.With the coordination of the central metal cobalt(Ⅱ)atom with the ligand and the oxygen atom of the bridging water molecule,it extends infinitely along the z-axis to form a three-dimensional porous network structure with honeycomb.The synthesis of this complex is expected to provide a potential functional material for the adsorption treatment of textile printing and dyeing wastewater.
