28_01/1989The cover picture shows the structure of hexa[bis(trimethylsilyl)methyl]hexagermaprismane. The synthesis of this first hexagermaprismane was an outcome of the search for polyhedranes with skeletal frameworks of heavy main-group elements. Further surprises can also be expected in the near future in this branch of inorganic chemistry, which has been fluorishing for some years now. In the molecule illustrated, which has D3h symmetry, all the Ge-Ge bonds are much longer than those in other polygermanes. A further surprising feature is that—other than in the carbon analogues—the bonds in the triangular units are longer than in the rectangular units. Further details of this chemical filigree are reported by H. Sakurai et al. on p. 55f.
