A fully symmetrical osmium tetrahedron consisting of twenty cubic‐close‐packed metal atoms constitutes the framework of dianion 1. There is no evidence for interstitial carbon or hydrogen atoms in the framework. Moreover, the OsOs distances approach those of elemental osmium. Cyclovoltammetric measurements indicate that 1 exhibits interesting electrochemical properties (see also the Highlight on p. 72).
