imine (–CH N–) function. All three complexes were characterized by 1H NMR and IR spectroscopy, together with elemental analysis. Furthermore, the solid-state structures of two complexes (2a and 2c) were determined using single crystal X-ray diffraction analysis. The diffraction analysis revealed that the ligand 1a binds with the Pt(II) ion in a monoanionic terdentate (N,N,N) fashion, offering a distorted
摘要配体bis-2,2'-(N-烷基氨基)偶氮苯1a–c与K2 [PtCl4]在甲醇中以1:1的比例反应生成了两种类型的Pt(II)配合物2a–b和2c。配体1a–b产生新的Pt(II)氨基偶氮偶氮配合物,而1c通过配体的一个仲胺(–CH2-NH–)的不寻常氧化脱氢形成亚胺(–CH N -) 功能。所有三种配合物均通过1 H NMR和IR光谱以及元素分析进行了表征。此外,使用单晶X射线衍射分析确定了两种络合物(2a和2c)的固态结构。衍射分析表明,配体1a以单阴离子三齿(N,N,N)的方式与Pt(II)离子结合,提供扭曲的正方形平面几何形状,其中第四个配位点由一个氯配体满足。相反,1c配体以双阴离子四齿(C,N,N,N)的方式与Pt(II)离子结合,从而提供了扭曲的正方形平面几何形状。几种较弱的非共价作用力负责改变晶格中的分子堆积。还检查了新配合物的氧化还原性质。
