Half-sandwich Ruthenium(II) arene complexes bearing the azo-azomethine ligands: Electrochemical, computational, antiproliferative and antioxidant properties

Publication date: 1 September 2018Source: Journal of Organometallic Chemistry, Volume 870Author(s): Ayşe İnan, Ali Burak Sünbül, Mesut İkiz, Seçil Erden Tayhan, Sema Bilgin, Mahfuz Elmastaş, Koray Sayın, Gökhan Ceyhan, Muhammet Köse, Esin İspirAbstractThree novel azo-azomethine ligands have been synthesized in an accomplished one-pot synthesis protocol. The mononuclear Ru(II) complexes of these azo-azomethine dyes were prepared and characterized by the combination of elemental analyses, IR, UV–Visible spectroscopy and 1H13C NMR spectra. Solid state structures of 3, 4 and 7 were determined by single crystal X-ray diffraction studies. The electrochemical and photoluminescence properties of the compounds were studied. The 1931 CIE (x,y) chromaticity coordinates of the ligands and their metal complexes were investigated and the x, y values of the compounds were found to be close to the National Television Standard Committee (NTSC) standard. Quantum chemical calculation of related ligands and complexes are performed at B3LYP/6-31G(d,p) and B3LYP/6-31G(d,p) (LANL2DZ) level in vacuum.In addition, the azo-azomethine ligands and their Ru(II) complexes were evaluated for both their in-vitro antibacterial activity by the disc diffusion method and antioxidant properties using ferric reduction power, DPPH free radical, and ABTS cation radical scavenging activities as in vitro. Radical scavenging activities of compounds 5–7 were found higher than BHT, BHA, and Trolox used a...
