Homotrinuclear ruthenium(ii) and rhodium(i) complexes of redox-active tris(ferrocenyl)arene-based tris-phosphanes.

ABSTRACT: Homotrinuclear complexes of the C ₃-symmetric tris(ferrocenyl)arene-based tris-phosphanes 1a-d with ruthenium(ii) ([1a-d(Ru)₃]) and rhodium(i) ([1a-d(Rh)₃]) were prepared and fully characterised. Complexes [1a-d(Ru)₃] and [1a-d(Rh)₃] are electrochemically active. The nature of the arene core in 1a-d ranging from benzene, 1,3,5-trifluorobenzene and mesitylene to s-triazine allows to fine-tune the exact oxidation potentials for tailoring the electrochemical response. With a BAr^F ₄ ^--based supporting electrolyte, a distinct separation of the three iron-centred oxidations of the ligand backbone is observable. Under these conditions, these oxidations are mostly reversible but, especially for th
