Descrição: Metal–metal double-π bonding in s-block metals has not been reported until now. The octahedral clusters of Be2(μ2-X)4 only possessing degenerate Be–Be double-π bonds were first achieved by an innovative concerted electron-donating strategy from the vertical plane of the Be–Be midpoint using four s1-type electron-donating ligands. Moreover, this novel strategy is universal and independent of electronegativity. Three typical clusters were discussed herein including Be2(BeF)4, Be2Li4 and Be2Cu4. Especially, WBIBe–Be in Be2Li4 reached up to 1.96. The significant π-bonding character was confirmed by various bond analysis strategies.
