They have been investigated as models of oligomeric and polymeric complexes of analogous composition. UV/Vis absorption spectroscopy and cyclic voltammetry indicate that Rh2(O2CCF3)4 possesses the strongest inductive effect of the three bimetallic tetracarboxylates examined in this study. Complex 1 was additionally characterized by single crystal X-ray analysis, revealing a Mo−Mo distance of 214.22(3) pm, which is elongated in comparison to Mo2(O2CCF3)4 [209.0(4) pm], and a Mo−N distance of 250.4(2) pm. Oligomers with backbones consisting of 1,1′-bis(4-pyridylethynyl)ferrocene (BPEF) and bimetallic tetracarboxylates, [M2(O2CR)4(BPEF)]n (M = Mo, R = CF3, 4; M = Rh, R = CH3, 5; M = Rh, R = CF3, 6), have been prepared by treating the bimetallic tetracarboxylates with BPEF in a 1:1 molar ratio. The terminal groups and the number of repeating units have been estimated by elemental analyses. The oligomeric complexes 5 and 6 are insoluble in all common solvents. Complex 4 dissolves in strongly coordinating donor solvents due to replacement of the BPEF ligands by solvent molecules.
