Abstract The role of Li x H y (Cs x H y ) molecules, which can be formed from seeding an alkali into a hydrogen plasma, is examined through ab initio calculations of the structure and stability of such species. The simplest alkali hydride, LiH, supports a bound anion for all internuclear separations. Larger structures, such as Li 2 H 2 and Li 3 H, do not support stable anions but exhibit thermodynamic stability as gas phase molecules. Their possible roles in dissociative attachment to form H − and/or Li − is examined.
