{Ge10Si[Si(SiMe3)3]4(SiMe32)Me}-: a Ge10Si framework reveals a structural transition onto elemental germanium.

The reaction of the metastable high temperature molecule GeCl synthesized via a co-condensation technique with LiSi(SiMe(3))3 leads to a metalloid Ge(10)Si cluster compound, in which the arrangement of the germanium atoms can be seen as a cutout from the structure of elemental germanium.
