Tetrazine Chelate Ligands Bridging Two [Ru(acac)(2)] Fragments: Mixed Valency and Radical Complex Formation
Original language description
Using bis(3-methyl-2-pyridyl)-1,2,4,5-tetrazine 1, 3-(2-pyrimidyl)-6-methyl-1,2,4,5-tetrazine 2 and bis(2-pyrimidyl)-1,2,4,5-tetrazine=bmtz as ligands, the complexes 3=[Ru(acac)(2)(1)], 4={[Ru(acac)(2)](2)(1)], 5={[Ru(acac)(2)](2)(bmtz)], and 6={[Ru(acac)(2)](2)(2)] were prepared and identified by structure analysis of crystallized material. The one-electron oxidized form 6(PF6) was also studied structurally, suggesting a Class II mixed-valent situation. The neutral dinuclear systems exhibit two reversible oxidation processes with comproportionation constants 10(9.2)<K-c<10(14.1) and one reduction which were analyzed UV/vis/NIR and EPR spectroscopically. Oxidation produces largely metal-based mixed-valent cations with very weak intervalence absorptions in the near IR whereas the electron uptake occurs at the tetrazine acceptor.
