Filling Gaps in the Series of Noninnocent Hetero-1,3-diene Chelate Ligands: Ruthenium Complexes of Redox-Active alpha-Azocarbonyl and alpha-Azothiocarbonyl Ligands RNNC(R ')E, E = O or S
Original language description
The series of 4-center unsaturated chelate ligands A=B-C=D with redox activity to yield (-)A-B=C-D- in two steps has been complemented by two new combinations RNNC(R')E, E = O or S, R = R' = Ph. The ligands N-benzoyl-N'-phenyldiazene = L-O, and N-thiobenzoyl-N'-phenyldiazene = L-S, (obtained in situ) form structurally characterized compounds [(acac)(2)Ru(L)], 1 with L = L-O, and 3 with L = L-S, and [(bpy)(2)Ru(L)](PF6), 2(PF6) with L = L-O, and 4(PF6) with L = L-S (acac(-) = 2,4-pentanedionato; bpy = 2,2'-bipyridine). According to spectroscopy and the N-N distances around 1.35 angstrom and N-C bond lengths of about 1.33 angstrom, all complexes involve the monoanionic (radical) ligand form. For 1 and 3, the antiferromagnetic spin spin coupling with electron transfer-generated Rum leads to diamagnetic ground states of the neutral complexes, whereas the cations 2(+). and 4(+) are EPR-active radical ligand complexes of Ru-II. The complexes are reduced and oxidized in reversible one-electro
