A profitable merger : The reaction of K 5 Bi 4 with ZnPh 2 yields the 20‐atom cluster [Zn@(Zn 8 Bi 4 )@Bi 7 ] 5− (see structure; zinc green, bismuth orange), which consists of a central zinc atom within a Zn 8 Bi 4 icosahedron (red) capped by seven bismuth atoms. Extensive amalgamation of the two types of atoms, reminiscent of an alloy, occurs in this intermetalloid cluster.
