Incorporation of a redox-passive bridge affords three identical redox systems in the triskelion-shaped, carbon-rich, polyvinylidenemetal complex 1. The complex was isolated from the activation of the tripodal polyyne 1,3,5-(HC≡CC<sub>6</sub> H<sub>4</sub> C≡C)<sub>3</sub> C<sub>6</sub> H<sub>3</sub> with [RuCl<sub>2</sub> ({(Ph<sub>2</sub> P)<sub>2</sub> C<sub>2</sub> H<sub>4</sub> }<sub>2</sub> ] and further converted into polyynylmetal complexes and a triple ferrocenyl-substituted ruthenium complex.
