M_3C_2 (M=Sc, La) clusters are produced by laser vaporization in a pulsed metal-cluster source and identified by photoionization mass spectrometry. Vibrationally resolved ion spectra are obtained with mass-analyzed threshold ionization (MATI) spectroscopy. The MATI spectra of M_3C_2 (M=Sc, La) exhibit a weak 0-0 transition, indicating a significant geometry difference between the neutral and ionized clusters. The ionization energies of Sc_2C_2 and La_3C_2 are measured to be 36398 (5) and 30051(5) Cm-1, respectively. In addition, the spectra of the two clusters display a number of vibrational intervals that are associated with M_3 deformations. Preliminary data analysis shows that both clusters have a C2v bi-pyramid structure in the neutral state and a D3h bi-pyramid structure in the ion state, and the spectra may be assigned to the ^1A'_1 (D3h)← ^2B_2 (C2v) transitions.
