Abstract

New complexes prepared by the reaction of N,N’-bis(3-methoxysalicylidenimino-1,3-diaminopropane) (H2L) with Ni(II), Zn(II) and Cu(II) ions are reported in this paper. The H2L ligand is structurally characterized by elemental analysis, NMR, infrared, UV-Vis spectroscopies, conductance and magnetic room temperature measurement. The mononuclear complex of Ni(II) (C19H24N2NiO6) is characterized by single X-ray diffraction. The compound crystallizes in the orthorhombic system in the space group Pnma with the unit cell parameters a = 7.3754(5) Å, b = 21.9576(13) Å, c = 11.5546(6) Å, α = 90°, β = 90°, γ = 90° The ligand H2L acts in tetradentate fashion in its di-deprotonated form.  Two coordinated water molecules complete the coordination sphere. The environment around the Ni(II) center is best described as an octahedral geometry.

N,N'-双(3-甲氧基水杨亚胺-1,3-二氨基丙烷)与镍(II)、铜(II)和锌(II)的配位:合成、晶体结构
本文报告了 N,N'-双(3-甲氧基水杨酰亚氨基-1,3-二氨基丙烷)(H2L)与 Ni(II)、Zn(II) 和 Cu(II) 离子反应制备的新配合物。通过元素分析、核磁共振、红外光谱、紫外可见光谱、电导和磁性室温测量,对 H2L 配体进行了结构表征。镍(II)的单核复合物(C19H24N2NiO6)通过单 X 射线衍射表征。该化合物在正方晶系中结晶,空间群为 Pnma,单胞参数为 a = 7.3754(5) Å,b = 21.9576(13) Å,c = 11.5546(6) Å,α = 90°,β = 90°,γ = 90°。 两个配位水分子完成了配位层。Ni(II) 中心周围的环境最适合描述为八面体几何。
