The first polyhedral aluminum subhalide Al 22 Br 20 ⋅20 L forms in the disproportionation of aluminum( I ) bromide solutions. The cluster is built up from an Al 12 icosahedron with ten exohedrally bound (formally divalent) Al atoms (see structure). Such a homoatomic framework is unknown for molecular compounds. Even for the element boron this framework is only found as a section from the β ‐rhombohedral element modification.
