    <dcterms:abstract xml:lang="eng">Four octahedral ruthenium(II) azoimine–quinoline complexes having the general molecular formula [RuII(Lsingle bondY)(bpy)Cl](PF&lt;sub&gt;6&lt;/sub&gt;) {Lsingle bondY = YC&lt;sub&gt;6&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;Ndouble bond; length as m-dashNC(COCH&lt;sub&gt;3&lt;/sub&gt;)double bond; length as m-dashNC&lt;sub&gt;9&lt;/sub&gt;H&lt;sub&gt;6&lt;/sub&gt;N, Y = H (1), CH&lt;sub&gt;3&lt;/sub&gt; (2), Br (3), NO&lt;sub&gt;2&lt;/sub&gt; (4) and bpy = 2,2′-bipyrdine} were synthesized. The azoimine–quinoline based ligands behave as NN′N″ tridentate donors and coordinated to ruthenium via azo-N′, imine-N′ and quinolone-N″ nitrogen atoms. The composition of the complexes has been established by elemental analysis, spectral methods (FT-IR, electronic, &lt;sup&gt;1&lt;/sup&gt;H NMR, UV/Vis and electrochemical (cyclic voltammetry) techniques. The crystal structure of complex 1 is reported. The Ru(II) oxidation state is greatly stabilized by the novel tridentate ligands, showing Ru(III/II) couples ranging from 0.93–1.27 V vs. Cp&lt;sub&gt;2&lt;/sub&gt;Fe/Cp&lt;sub&gt;2&lt;/sub&gt;Fe&lt;sup&gt;+&lt;/sup&gt;. The absorption spectrum of 1 in dichloromethane was modeled by time-dependent density functional theory (TD-DFT).</dcterms:abstract>
