RuII(9aneS3)(L)(DMSO)ClO4 (1ClO4) (9aneS3 = 1,4,7-trithiacyclononane, HL = 9-hydroxyphenalenone, DMSO = DMSO) was structurally characterized to reveal almost equal C-O bond distances of coordinated L-, suggesting a delocalized bonding situation of the b-diketonato ligand. The DMSO ligand is coordinated via the sulfur atom in the native (1+) and reduced states (1 and 1-) as was revealed by x-ray crystallog. and by DFT calcns. Cyclic voltammetry of 1+ exhibits two close-lying 1-electron oxidn. waves at 0.77 V and 0.94 V, and two similarly close 1-electron redn. processes at -1.43 V and -1.56 V vs. SCE in CH2Cl2. The electronic structures of 1n in the accessible redox states were analyzed via expts. (EPR and UV-visible-NIR spectroelectrochem.) and by DFT/TD-DFT calcns., revealing the potential for bidirectional noninnocent behavior of coordinated L·/-/·2-.
