The exceptionally sensitive crystalline compound bis( o ‐phenylenedioxy)silane (1) was synthesized in 1979 by Meyer and Nagorsen as the first molecule with planar tetracoordinated silicon. In the absence of a detailed X‐ray structure analysis, statements about the structure of (1) were based on arguments of crystallographic symmetry. According to Dunitz this argumentation has two weak points. Moreover, the chemical identity of the crystals examined does not appear to be established beyond all doubt. Nevertheless, (1) could be the first compound with planar tetracoordinated silicon.
