Abstract

The title compound, C56H56Ge4O 2·2CH2Cl2 or Tol8Ge 4O2·2CH2Cl2 (Tol = p-CH 3C6H4), was obtained serendipitously during the attempted synthesis of a branched oligogermane from Tol3GeNMe2 and PhGeH3. The mol-ecule contains an inversion center in the middle of the Ge4O2 ring which is in a chair conformation. The Ge - Ge bond distance is 2.4418 (5) Å and the Ge - O bond distances are 1.790 (2) and 1.785 (2) Å. The torsion angles within the Ge4O2 ring are -56.7 (1) and 56.1 (1)° for the Ge - Ge - O - Ge angles and -43.9 (1)° for the O - Ge - Ge - O angle. © Amadoruge et al. 2009.
