The photoelectron spectra of FeC[sub 2][sup -] and FeC[sub 2]H(D)[sup -] are studied at 3.49 eV photon energy. The electron affinities of FeC[sub 2] and FeC[sub 2]H(D) are determined to be 1.91(10) and 1.41(5) eV, respectively. An excited state of FeC[sub 2] at 1 eV above its ground state is also observed. Only one major detachment channel is observed for FeC[sub 2]H(D)[sup -]. A vibrationally resolved spectrum at 2.33 eV photon energy for FeC[sub 2]D[sup -] is also obtained with a Fe-C stretching progression, yielding a vibrational frequency of 500(100) cm[sup -1]. The spectra provide unique information on the bonding between Fe and C[sub 2] and C[sub 2]H(D). 18 refs., 3 figs., 1 tab.
