Reactions of Cp*Ru(κ2-N(R){double bond, long}C(R′)NR) (1a; R = iPr, R′ = Me, 1b; R = tBu, R′ = Ph) with TCNE initially give dark green colored intermediary species, which are readily converted to brown colored "η2-C" coordination complexes, Cp*Ru(κ2-N(R){double bond, long}C(R′)NR)(η2-TCNE) (3a; R = iPr, R′ = Me, 3b; R = tBu, R′ = Ph). These "η2-C" complexes are characterized by spectroscopy and crystallography. A stable ruthenium amidinate having a "κ1-N"-coordinated TCNE, Cp*Ru(κ2-N(tBu){double bond, long}C(Mes)NtBu)(κ1(N)-TCNE) (2c), is synthesized by treatment of Cp*Ru(κ2-N(tBu){double bond, long}C(Mes)NtBu) (1c) with TCNE, the structure of which is unequivocally confirmed by X-ray structure determination and the charge transfer nature is supported by ESR analysis. Close analogy in IR and UV-Vis spectroscopy of 2c with the dark green colored intermediary species formed from 1b suggests that this is "κ1-N" ruthenium amidinate, which is rearranged to the "η2-C" complex 3b.
