Abstract

Graphical abstract: Several new Ru(II) polypyridyl complexes of the novel tetradentate thioether 1, 2-bis[3′-(2″-pyridyl)-1′-thiapropyl]benzene (Ppes) form from the dinuclear ruthenium(II) complex [{Ru(Ppes)}2 (µ-Cl)2 ] 2+ via reaction with various bidentate diimines. Facile symmetrical bridge cleavage occurs, producing mononuclear complexes of the form [Ru(Ppes)(L)] 2+, where L is the bidentate diimine.

Redox chemistry shows single-electron Ru(II) → Ru(III) oxidations over a wide range of potentials.
