Abstract

© 2018 Elsevier B.V. A new labile areneruthenium sulfide complex, [(C6H6)3Ru3S2](PF6)2 (1), was prepared and characterized both in solid state and in solution. Light-driven de-coodination of the arene ligands has been demonstrated. Two new polynuclear areneruthenium complexes, [(C6H6)4Ru5S4](PF6)2·2CH3CN (2) and [(C6H6)4Ru4S5](PF6)2·1.25CH3CN·0.5H2O (3), were obtained from 1 and structurally characterized. Redox behaviour of [(C6H6)3Ru3S2](PF6)2 and [Ru5S4(C6H6)4](PF6)2·2CH3CN was studied by cyclic voltammetry and reveals one reversible reduction wave.
