一维链状铜(Ⅱ)配合物的合成、晶体结构及热稳定性研究(英文)

Synthesis,Crystal Structure and Thermal Property of a 1D Chain-Like Copper(Ⅱ) Complex

通过一种新的肟类配体HL(HL=1-(4-{[(E)-3-乙氧基-2-羟苯亚甲基]氨基}苯乙酮肟)与一水合乙酸铜反应,合成了一种铜(Ⅱ)配合物[Cu(L)2].CH3OH。X射线单晶结构分析表明该配合物是一种单核配合物,其中铜(Ⅱ)原子以四配位的形式分别与2个单肟配体的酚氧原子和亚胺氮原子结合,形成稍微扭曲的平面四边形几何构型。O和N配位原子互为反式,所形成的Cu1N2O2平面和Cu1N4O5平面的二面角为23.33(3)°。在这个晶体结构中,每1个配合物分子分别与近邻的2个配合物分子通过O-H…O氢键连接,沿b轴形成了1个一维的无限延伸的链状结构。

A Cu（Ⅱ）complex, [Cu（L）2] .CH3OH, has been synthesized via the complexation of copper（1） acetate monohydrate with a new oxime-type ligand （HL=l-（4-{[（E）-3-ethoxyl-2-hydroxybenzylidene]amino}phenyl）ethanone oxime）. X-ray crystal structure determination of the Cu（Ⅱ） complex shows that is a mononuclear complex. The Cu（Ⅱ） atom is four-coordinated by the phenolate O atoms and imine N atoms from two deprotonated oxime-type ligands, in a slightly distorted square-planar geometry. The O- and N-donor atoms are mutually trans and the dihedral angle between the two coordination planes （CulN2O2 and CulN405） is 23.33（3）. In the crystal structure, each complex molecule links two other adjacent complex molecules into an infinite one-dimensional structure along the b axis through intermolecular O-H…0 hydrogen bonds.
