State-of-the-art electronic structure calculations provide the likelihood
of the availability of YLi.sub.3N.sub.2, ZrLi.sub.3N.sub.2,
NbLi.sub.3N.sub.2, MoLi.sub.3N.sub.2, TcLi.sub.3N.sub.2,
RuLi.sub.3N.sub.2, RhLi.sub.3N.sub.2, GeLi.sub.3N.sub.2,
InLi.sub.3N.sub.2, and SnLi.sub.3N.sub.2 as compounds for reaction with
hydrogen under suitable conditions. Such calculations also provide the
likelihood of the availability of YLi.sub.3N.sub.2H.sub.n,
ZrLi.sub.3N.sub.2H.sub.n, NbLi.sub.3N.sub.2H.sub.n,
MoLi.sub.3N.sub.2H.sub.n, TcLi.sub.3N.sub.2H.sub.n,

InLi.sub.3N.sub.2H.sub.n, SnLi.sub.3N.sub.2H.sub.n, and
SbLi.sub.3N.sub.2H, (here n is an integer having a value of 1-6) as solid
hydrides for the storage of hydrogen. These materials offer utility for
hydrogen storage systems.
