水热条件下,合成了1个铜髤配位聚合物[Cu(L)(4,4′-bpy)(HCOO)(H2O)]n(HL=苯并三氮唑-1-氧基乙酸,4,4′-bpy=4,4′-联吡啶),并通过元素分析、红外光谱,热重分析,X-射线粉末衍射和X-射线单晶衍射对其进行了表征。晶体结构表明,配合物属三斜晶系,空间群P1,晶胞参数:a=0.820 26(16)nm,b=1.128 3(2)nm,c=1.159 7(2)nm,α=76.50(3)°,β=70.88(3)°,γ=76.97(3)°,V=0.973 0(3)nm3,Z=2。铜髤分别与来自2个4,4′-bipy的2个氮原子、1个苯并三氮唑-1-氧基乙酸的1个氧原子、1个甲酸根中1个氧原子和1个水分子中的1个氧原子配位,形成变形的四方锥的配位构型。由于4,4′-bipy的桥联作用,配合物在空间形成了一维链状结构,该一维链又通过分子间O-H…N和分子内O-H…O氢键作用形成了二维层状结构。
Under the hydrothermal conditions, a Cu (L) (4,4’-bpy) (HCOO) (H2O)] n (HL = benzotriazole-1-oxoacetic acid , 4,4’-bpy = 4,4’-bipyridine) and characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis, X-ray powder diffraction and X-ray single crystal diffraction. The crystal structure shows that the complex belongs to the triclinic system with the space group P1, with unit cell parameters of a = 0.820 26 (16) nm, b = 1.128 3 (2) nm, c = 1.159 7 (3) °, β = 70.88 (3) °, γ = 76.97 (3) °, V = 0.973 0 (3) nm3 and Z = 2. Copper 髤 respectively from two 4, 4’-bipy two nitrogen atoms, a benzotriazole-1-oxoacetic acid one oxygen atom, a formate oxygen atom and a One oxygen atom in water molecules coordinate to form a deformed tetragonal conformation. Due to the bridging effect of 4,4’-bipy, the complex forms a one-dimensional chain structure in space, which forms a two-dimensional layered structure through the intermolecular OH ... N and intramolecular OH ... O hydrogen bonding structure.
