Synthesis and determination of thermal decomposition of biological active arene ruthenium compounds containing bisbenzimidazole linker

Aren ruthenium complexes have been known for 50 years. The initial arene was initially found as a catalyst after synthesis and characterization of ruthenium complexes. They were then determined to be biologically active with the emergence of bio-organometallic chemistry. In this study, [Ru4(p-cymene)4(μ-NՈN)2(μ-OOՈOO)2][CF3SO3)4] (NՈN= Butylene-1,4-bisbenzimidazole (bbim)) biologically active tetranuclear arene complex compounds, reacting Ru2(p-cymene)2(μ-OOՈOO) Cl2 (OOՈOO= 2,5-dioxido-1,4- benzoquinon (dobq), 1,4-benzoquinon-2,5-dichloro-3,6-dioxido (dClbq), 1,4 benzoquinon-2,5-dibromo-3,6-dioxido (dBrbq), oxalato (oxa) and 5,8-dioxido-1,4-naphtoquinonato (donq)) with silver trifluoromethanesulfonate, followed by the addition of the corresponding NՈN linkers. The biologically active arene ruthenium compounds was characterized by standard techniques including IR, UV-VIS, 1H NMR, 13C NMR spectroscopy and ESI-MS spectrometry. Thermal decomposition measurement data of arene ruthenium compounds were examined. These measurements were made by Thermogravimetric analysis (TGA) and Differential thermal analysis (DTA) techniques.
