Lithium beryllide

Lithium beryllide is a hypothetical intermetallic compound of lithium and beryllium that may have several possible compositions, including LiBe, LiBe2, Li2Be, LiBe3, Li3Be, Li2Be3, Li3Be2, LiBe4 and Li4Be.[1] Computational methods indicate that some of these compositions may be superconductive under very high pressure and low temperature.[1][2][3]
