Synthesis and characterization of Ru(III) complexes with thiosemicarbazide-based ligands

Abstract

Three Ru(III) complexes general formula Na[RuL2] (where L = dibasic tridentate thiosemicarbazone ligands) have been synthesized by reacting RuCl3 with thiosemicarbazide-based ligands with ONS donors. Ligands coordinated as an ONS tridentate dianion through the oxygen atom of the deprotonated phenolic OH-group, azomethine nitrogen and sulfur atom of thioamide group. The structures have been characterized by mass spectrometry and infrared spectroscopy confirming 1:2 metal-to-ligand ratios.
