Abstract
The organometallic conjugated complex H(C C)(2)W] CC CC W](C 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.
