Fig. 8: Molecular structure of the anionic cluster moiety [^MeHyp₃Si₉]⁻ in [K(2.2.2-crypt)][^MeHyp₃Si₉]·thf (2a).

Anisotropic displacement ellipsoids of silicon (blue) are drawn at 50% probability. Carbon (grey) is displayed as spheres of an arbitrary radius and hydrogen atoms are omitted for clarity.
