文摘

Group 14 elements (Si, Ge, Sn, and Pb) were applied as spacers to construct new dinuclear organometallic [5]trovacenyl derivatives [(η⁷-C₇H₇)V(η⁵-C₅H₄)]₂MR₂ (2^··, 3^··, 4^··, and 5^··; M = Si, Ge, Sn, Pb; R = Me or Ph), which have been characterized by mass spectrometry, elemental analysis, and/or X-ray diffraction analysis. A systematic electrochemical study by cyclic voltammetry indicates weak intramolecular electronic communication between two vanadium centers in the order of Si (2^··) < Ge (3^··) < Sn (4^··) < Pb (5^··). The impact of the substituents and the solvents on the electrochemical behavior of [(η⁷-C₇H₇)V(η⁵-C₅H₄)]₂SnMe₂ (5^··) and [(η⁷-C₇H₇)V(η⁵-C₅H₄)]₂SnPh₂ (9^··) was evaluated.
