Abstract
The simplest alkali metal acetylides MCCH were made in the gas phase for the first time (see drawing), and their bond lengths were determined by millimeter/submillimeter spectroscopy of their isotopomers. The M-C bond lengths r(CM) are the shortest known for organoalkali metal compounds. In the case of LiCCH, the experimentally determined Li-C distance of 1.888 Å has an estimated accuracy of ±0.0005 Å, which should allow a rigorous test of theoretical methods.
