A piperazine derivative, ethyl 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 two ligand Heptpc and N site of two pyridine molecules. On the basis of various techniques used for the characterizations of the complexes, we found that the most possible geometry of the Ni(II) and Zn(II) complexes are distorted octahedral and of the Cd(II) complex is distorted tetrahedral.

Cationic, chiral arene ruthenium complexes of the type [Ru(η6-cym)(PPh3){κ2N,S-PhNC(S)R}]BPh4 were prepared in high yields by refluxing a mixture containing [(η6-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.
