The cover picture shows the cationic cluster [Ru(Bi8)2]6+, which is part of the metal-rich bromide Bi39.67(7)Ru2Br35.0(2). The isolated Bi82+ polycation was first described by Bernt Krebs in 1982. Here two of them coordinate a ruthenium(II) cation. The η4-coordination can be regarded as a multi-center bonding, in which a combination of Bi-6p orbitals provides intra-ligand Bi?Bi bonding and simultaneously acts as a donor towards the transition metal atom. A transfer of six electrons per polycation and thus an 18-electron situation for the central atom can be inferred. More details are discussed in the article by Ruck et al. on pp. 2401ff.
