Pulsed-laser evaporated Al and C atoms have been reacted in a condensing argon stream to form AlC, Al2C, and AlCCAl. These molecules were identified from carbon-13 substitution and by comparing observed and CASSCF-calculated frequencies. The analogous Al atom reaction with C2H2 gave HCCAl in higher yield than in earlier thermal Al experiments with C2H2 following photolysis of the AlC2H2 complex. These aluminum acetylide molecules contain C=C bonds that are calculated to be slightly longer than that for C2H2.
