Synthesis, structure, antibacterial studies and DFT calculations of arene ruthenium, Cp∗Rh, Cp∗Ir and tricarbonylrhenium metal complexes containing 2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline ligand

A series of mononuclear platinum group and tricarbonylrhenium(I) metal complexes have been synthesized with the metal precursors and 2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline (L). These water soluble platinum group metal complexes display good antibacterial activities against the three different bacteria, Staphylococcus aureus subsp. aureus, Staphylococcus epidermidis and Escherichia coli.
