We propose new methodologies for stabilizing all-metal antiaromatic clusters like: Al4Li4. We demonstrate that these all-metal species can be stabilized by complexation with 3d-transition metals very similar to its organic counterpart, C4H4. Complexation to transition metal ions reduce the frontier orbital energies and introduces aromaticity. We consider a series of such complexes [η4(Al4Li4)-Fe(CO)3, η2σ2(Al4Li4)-Ni and (Al4Li4)2Ni] 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.
