A good agreement is found among the structural parameters of both the phases with experimentally evaluated parameters. For both the phases metallic conductivity is observed while Nb3Be phase is more conducting than that of Nb3Be2 phase. Evaluated DOS at Fermi level indicates that Nb3Be2 phase is electrically more stable than Nb3Be phase. For both phases Nb-4d states is mostly responsible for metallic conductivity.
