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。
A new zinc (Ⅱ) coordination polymer [Zn (PCPA) 2 (4,4’-bipy) (H2O)] n (PCPA = 4-chlorophenoxyacetic acid, 4,4 ’-bipy = 4,4’-bipyridine) and characterized by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy, thermogravimetry, X-ray powder diffraction and X-ray single crystal diffraction. Zinc (Ⅱ) complexes with two nitrogen atoms from two 4,4’-bipy, three oxygen atoms from three 4-chlorophenoxyacetic acids, and one oxygen atom in one water molecule respectively to form a deformation Octahedral coordination configuration. Due to the bridging effect between 4-chlorophenoxyacetic acid and 4,4’-bipy, the complex forms a two-dimensional layered structure in space, where the OH ... O hydrogen bonds existing in the two-dimensional layered structure play a stabilizing role Role.
