Cationic, chiral arene ruthenium complexes of the type [Ru(eta(6)-cym)(PPh3)kappa N-2,S-PhNC(S)R}]BPh4 were prepared in high yields by refluxing a mixture containing [(eta(6)-cym)RuCl2](2), Ph3P, PhNHC(S)R, NaBPh4 and Et3N in MeOH. A series of seven complexes with different thioamide ligands was prepared and fully characterised by spectroscopic methods including NMR spectroscopy and electrospray mass spectrometry. The solid-state structures of two complexes were determined by single crystal X-ray diffraction. (C) 2008 Elsevier B.V. All rights reserved.

4-phenylthiocarbamoyl piperazine-1-carboxylate and its Ni(II), Zn(II) and Cd(II) complexes have been synthesized and characterized by elemental analyses, magnetic susceptibility measurement, UV–Visible, FTIR, Raman spectroscopic and DFT methods. The Ni(II) and Zn(II) bind through the N and S sites of the two ligand Heptpc and N site of two pyridine molecules. However, the Cd(II) binds through the only N sites of the
摘要 合成了哌嗪衍生物 4-苯基硫代氨基甲酰基哌嗪-1-羧酸乙酯及其 Ni(II)、Zn(II) 和 Cd(II) 配合物,并通过元素分析、磁化率测量、紫外-可见光、FTIR、拉曼光谱和 DFT 方法。Ni(II) 和 Zn(II) 通过两个配体 Heptpc 的 N 和 S 位点以及两个吡啶分子的 N 位点结合。然而,Cd(II) 仅通过两个配体 Heptpc 的 N 位点和两个吡啶分子的 N 位点结合。基于用于表征配合物的各种技术,我们发现 Ni(II) 和 Zn(II) 配合物的最可能几何形状是扭曲的八面体,而 Cd(II) 配合物的最可能的几何形状是扭曲的四面体。
