Preparation and characterization of four novel 2,6-diacetylpyridinebis(4N-tolylthiosemicarbazonato) palladium(II) and platinum(II) complexes, [PdL1–2] and [PtL1–2], are described. All compounds have been characterized by elemental analysis and by IR and NMR spectroscopy, and the crystal and molecular structures of complexes [PdL2] and [PtL2] have been determined by a single crystal X-ray diffraction

the [PtL1] complex obtained, led to the isolation of the novel platinumcomplex, [PtL2], which was structurally characterized by single crystal X-ray diffraction. The molecular structure shows that the ligand has undergone an unexpected chemical transformation viz. reduction of one of the terminal phenyl rings into cyclohexyl. The resulted asymmetrical ligand acts a dianionic tetradentate donor, coordinating
摘要 2,6-二乙酰基吡啶双(4N-o-甲苯基氨基硫脲),H2L1 与 K2PtCl4 反应,并在 DMSO/MeOH 中进一步重结晶得到的 [PtL1] 配合物,分离出新型铂配合物 [PtL2],其结构通过单晶 X 射线衍射表征。分子结构表明配体发生了意想不到的化学转化,即。将末端苯环之一还原为环己基。所得的不对称配体作为二价阴离子四齿供体,通过 Npyridinic 原子和 Niminic 和来自一个缩氨基硫脲臂的 S 原子与铂(II)中心配位,第四个配位位置由 Nhydrazinic 原子占据另一只手臂。
