| 摘要: 水热条件下，合成了1个铜（Ⅱ）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（Ⅱ）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。 |

| Abstract: A 1D complex [Cu(L)(4,4'-bpy)(HCOO)(H2O)]n (HL=(1-Hydroxybenzotriazole)-o1-acetic acid, 4,4'-bpy=4,4'-bpyridine) has been synthesized under hydrothermal conditions and structurally characterized by elemental analysis, IR spectra, thermal analyses, powder X-ray diffraction and single crystal X-ray diffraction. The title complex belongs to triclinic with space group P1, 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. The copper(Ⅱ) ion is five-coordinated with two nitrogen atoms from two 4,4'-bpy, one oxygen atom from one HL, one oxygen atom from one formate and one water oxygen atom, forming a square-pyramidal configuration. The Cu(Ⅱ) centres are bridged by Cu(Ⅱ)-N coordination bond through 4,4'-bpy ligands resulting in the formation of 1D chain structure. Then the 1D chains are further packed into 2D layer structure by intermolecular O-H…N hydrogen bonds and intramolecular O-H…O hydrogen bonds. CCDC: 850113. |
