Ionic Donor-Acceptor Chain Derived from an Electron-Transfer Reaction of a Paddlewheel-Type Diruthenium(II, II) Complex and N,N'-Dicyanoquinonediimine.

A new ionic donor-acceptor (D+ A- ) chain compound, [{Ru2 (2,6-(CF3 )2 PhCO2 )2 (p-PhPhCO2 )2 }DMDCNQI] (1; 2,6-(CF3 )2 PhCO2- =2,6-bis(trifluoromethyl)benzoate; p-PhPhCO2- =4-biphenylcarboxylate; DMDCNQI=2,5-dimethyl-N,N'-dicyanoquinonediimine) was isolated and structurally characterized. It represents the first of this type of ionic chain compounds.
