| 摘要: 合成了一种不对称Salamo型配体5-甲氧基-6’-羟基-2，2’-[乙二氧双(氮次甲基)]二酚(H3L)及其四核锌(Ⅱ)配合物[Zn4L2(CH3OH)2(OAc)2]，并通过X-射线单晶衍射分析确定了其晶体结构。其中配体呈现一种“V”构型，两个苯环单元的二面角为 85.71(3)°，可近似认为是垂直的；而在配合物晶体结构中，金属离子有两种配位构型方式：一种为三角双锥构型，另一种为四方锥构型。配合物通过分子间的氢键作用形成了一个无限延伸的二维结构。 |

| Abstract: An asymmetrical Salamo-type ligand, 5-methoxy-6'-hydroxy-2,2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H3L), and its Zn(Ⅱ) complex, [Zn4L2(CH3OH)2(OAc)2], have been synthesized and structurally characterized by X-ray diffraction methods. X-ray crystallographic analyses reveal that the ligand adopts a V-shaped configuration, in which the two benzene rings are approximately perpendicular, making a dihedral angle of 85.71(3)°; the Zn(Ⅱ) complex adopts two different kinds of coordination geometries: trigonal bipyramidal and square pyramidal geometries. Meanwhile, each Zn(Ⅱ) complex molecule links four other molecules to form an infinite 2D layer structure through intermolecular hydrogen bond interactions. CCDC: 954985, H3L; 954984, Zn(Ⅱ) complex. |
