Isolated, nearly cubic Hg 8 clusters (“mercubanes”) have now been identified for the first time in the rubidium amalgam Rb 15 Hg 16 . Metallic, golden single crystals of this previously unknown compound were produced in the course of an unsuccessful attempt to synthesize RbHg. The geometry of the cluster suggests that electron transfer from the electropositive rubidium produces a chemical bond between mercury atoms that exhibits primarily σ p (6p) character rather than the σ s character familiar from the classical mercury polycations Hg n 2⊕ .
