Single-electron transfer to the p (C:C)-bonded tetracyanoethylene (TCNE) ligand in the blue complex with W(CO)5 leads to a yellow isomerized anion radical product in which TCNE- coordinates via one nitrile N lone pair. The high-resoln. EPR, UV/visible and IR data of the singly reduced complex clearly illustrate the lowered symmetry and diminished p-back-donation in the anionic form. Cyclic voltammetric expts. at variable scan rates show two distinctly sep. second redn. processes of the n- and s-coordinated complexes in what appears to be an organometallic example of mol. hysteresis (Sano, M. and Taube 1991). on SciFinder(R)
