The Be–Be bond has long represented a ‘missing link’ between the H–H bond of dihydrogen and the B–B bond of diborane(4) species. Now, a complex with a polarized Be–Be bond that acts as a source of the beryllyl anion is reported. This work also reveals similarities between the homo-elemental linkages of boron and beryllium.

极化 Be-Be 键


Be-Be 键长期以来一直代表着二氢的 H-H 键与乙硼烷 (4) 物质的 B-B 键之间的“缺失环节”。现在，报道了一种具有极化 Be-Be 键的络合物，可作为铍基阴离子的来源。这项工作还揭示了硼和铍的同质元素连接之间的相似性。
