Hexasupersilyloctaindane (tBu(3)Si)(6)In(8)- A Compound with a Novel In(8) Cluster Framework.
A doubly capped In(6) octahedron characterizes the structure of the dark green octaindane (tBu(3)Si)(6)In(8) (see picture), which is obtained from (C(5)Me(5))In and tBu(3)SiNa in pentane at -78 degrees 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.
