摘要 水热条件下,合成了一个新的锌(Ⅱ)配位聚合物[Zn(PCPA)2(4,4′-bipy)(H2O)]n(PCPA=4-氯苯氧乙酸,4,4′-bipy=4,4′-联吡啶),并通过元素分析、红外光谱、紫外光谱、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。锌(Ⅱ)分别与来自2个4,4′-bipy的2个氮原子、3个4-氯苯氧乙酸的3个氧原子和1个水分子中的1个氧原子配位,形成变形的八面体的配位构型。由于4-氯苯氧乙酸和4,4′-bipy的桥联作用,配合物在空间形成了二维层状结构,在此二维层状结构中存在的O-H…O氢键起到了稳定结构的作用。 The title complex [Zn(PCPA)2(4,4'-bipy)(H2O)]n with p-chlorophenoxyacetic acid (PCPA), 4,4'-bipyridine (4,4'-bipy) has been hydrothermally synthesized and characterized by elemental analysis, IR spectra, UV spectra, thermal analyses, powder X-ray diffraction and single crystal X-ray diffraction. The zine(Ⅱ) ion is six-coordinated with two nitrogen atoms from two 4,4'-bipy, three oxygen atoms from three PCPA and one water oxygen atom, forming a slightly distorted octahedral configuration. The complex molecules form a 2D layer structure through bridged PCPA and 4,4'-bipy which is consolidated by O-H...O hydrogen bonds. CCDC: 850113.
