Bis-allenylidene metal complex and unique related radical with delocalization of one electron over both trans carbon-rich chains.
We report the preparation of the first real bis(allenylidene) metal complex trans-[Ph2C=C=C=Ru=C=C=CPh2(dppe)2]2+, and its one electron reduction that gives a stable radical with the unpaired electron delocalized over both trans carbon-rich chains linked by the ruthenium atom, on the basis of spectroscopic and DFT, QM(DFT)/MM computational studies.
