以邻氨基苯磺酸与吡啶-2-甲醛进行缩合得到席夫碱配体(KL),然后与Cu(AcO)2.H2O进行配位反应,得到了席夫碱配合物[Cu(L)2][Cu’(L)2].CH3OH.3 H2O,用元素分析、FT-IR和X-射线单晶衍射进行了表征。结果表明,配合物属于单斜晶系,P21/c空间群。配合物的一个独立单元由三个晶格水分子、一个晶格甲醇分子和两个不同的单核铜单元构成。有趣的是,这两个单核铜单元的组成完全相同但配位模式不同,它们均由一个铜离子和两个脱质子的席夫碱配体组成,其中一个单核铜单元中的两个磺酸基均参与了配位,另一个则只有一个磺酸基配位。
Schiff base ligand (KL) was synthesized by the condensation of o-aminobenzenesulfonic acid with pyridine-2-carboxaldehyde and then complexed with Cu (AcO) 2] [Cu ’(L) 2] .CH3OH.3 H2O was characterized by elemental analysis, FT-IR and single crystal X-ray diffraction. The results show that the complex belongs to the monoclinic space group P21 / c. An individual unit of a complex consists of three lattice water molecules, a lattice methanol molecule, and two different mononuclear copper units. Interestingly, the two mononuclear copper units are identical in composition but different in coordination mode and consist of one copper ion and two deprotonated Schiff base ligands, two of which are mononuclear copper units Sulfonic acid groups are involved in the coordination, the other is only a sulfonic acid group coordination.
