  We propose new methodologies for stabilizing all-metal antiaromatic clusters
like: Al$_{4}$Li$_{4}$. We demonstrate that these all-metal species can be
stabilized by complexation with 3d-transition metals very similar to its
organic counterpart, C$_4$H$_4$. Complexation to transition metal ions reduce
the frontier orbital energies and introduces aromaticity. We consider a series
of such complexes [$\eta$$^4$(Al$_4$Li$_4$)-Fe(CO)$_3$,
$\eta$$^2$$\sigma$$^2$(Al$_4$Li$_4$)-Ni and (Al$_{4}$Li$_{4}$)$_{2}$Ni] and
make a comparison between the all-metal species and the organometallic
compounds to prove conclusively our theory. Fragmentation energy analysis as
well as NICS support similar mechanism of complexation induced stability in
these all-metal molecules.
