A doubly capped In 6 octahedron characterizes the structure of the dark green octaindane ( t Bu 3 Si) 6 In 8 (see picture), which is obtained from (C 5 Me 5 )In and t Bu 3 SiNa in pentane at −78°C. In1/In1′ are the capping atoms, and In2/In2′ form the apexes of the stretched In 6 octahedron. Thus, in agreement with the results of ab initio calculations, the compound can be classified as a hypoprecloso ‐indane.
