The structure of [Ir(CO)(PPh[sub 3])[sub 2]][sub 2][TCNE][center dot]MeCN has been determined and confirms that [mu][sub 2]-[TCNE][sup 2[minus]] is N-bound to a pair of Ir[sup I]'s. The 1.478-[Angstrom] central C-C bond is comparable to the separation of 1.49 [Angstrom] observed for the free [TCNE][sup 2[minus]] ion while the 67.2[degrees] dihedral angle is characteristic of the free rotation along the center C-C bond. The [nu][sub C[triple bond]N] vibrational spectra have absorptions at 2176 m and 2097 vs cm[sup [minus]1] which are blue-shifted by 72 and 28 cm[sup [minus]1], respectively, from that reported for the isolated [TCNE][sup 2[minus]]. 13 refs., 1 fig., 1 tab.
