An iron-capped metal-organic polyyne: {[Fe](C[triple bond]C)2[W][triple bond]CC[triple bond]CC[triple bond][W](C[triple bond]C)2[Fe]}.
The organometallic conjugated complex H(C[triple bond]C)(2)[W][triple bond]CC[triple bond]CC[triple bond][W](C[triple bond]C)(2)H {[W] = W(dppe)(2); dppe = 1,2-bis(diphenylphosphino)ethane} containing a ditungstenatetradecaheptayne unit was synthesized by utilizing a new and efficient coupling method. The stannylated derivative was converted to the tetranuclear complex, which exhibits efficient long-range electron transfer.
