Abstract

Amine Diimine Ruthenium X-ray structure
ORTEP drawing of the [Ru(Tren)(Phen)]2+ cation: synthesized through the treatment of Ru(Phen)(DMSO)2Cl2 with an equivalent of tris(2-aminoethyl)amine (Tren). [Display omitted] •Ru(II) complexes of tris(2-aminoethyl)amine (Tren) and diethylenetriamine (Dien).•Single-electron Ru(II)→Ru(III) oxidations over a wide range of potentials.•Development of Lever parameters for Tren and Dien. Several new Ru(II) complexes of tris(2-aminoethyl)amine (Tren) and diethylenetriamine (Dien) have been prepared using Ru(PPh3)3Cl2 and [(CH3)4N]2[Ru(Phen)Cl4] (1) as starting materials. The reaction of Tren or Dien with Ru(PPh3)3Cl2 leads to the formation of either the [Ru(Tren)(PPh3)Cl]Cl (2) or the Ru(Dien)(PPh3)Cl2 (4) complex, of which the latter then reacts further with a heterocyclic diimine (N–N) ligand to yield [Ru(Dien)(PPh3)(N–N)]Cl2. Addition of Tren or Dien to solutions of the [(CH3)4N]2[Ru(Phen)Cl4] complex replaces the coordinated chlorides with the N-donor ligand, forming [Ru(Tren)Phen](ClO4)2 (3) and [Ru(Dien)(Phen)Cl]Cl (5) respectively. Redox chemistry shows single-electron Ru(II)→Ru(III) oxidations over a wide range of potentials.
