The complexes mer- (X = Cl or Br, L = PMe2Ph or AsMe2Ph) have been re-examined and assignments for their UV/VIS spectra proposed.Attempts to prepare analogues with X = I or L = SbR3 have been unsuccessful.Cyclic voltammetry revealed only irreversible oxidation and reduction processes and chemical oxidation with halogens resulted in decomposition to 2-, in contrast to the chemistry of related osmium compounds.The crystal structures of mer- (X = Cl or Br) have been determined and confirm the geometrical isomer formed.Crystal structures were also determined for (X = Br, L = PMe2Ph or AsMe2Ph; X = I, L = AsMe2Ph) obtained by decomposition of mer- in solution, which are the first structurally characterised examples of Ru25+ dimers of this type with bromide or iodide co-ligands.The structures are consistent with a formal Ru-Ru bond order of 1/2.
