RESUMO
The title compound, C(56)H(56)Ge(4)O(2)·2CH(2)Cl(2) or Tol(8)Ge(4)O(2)·2CH(2)Cl(2) (Tol = p-CH(3)C(6)H(4)), was obtained serendipitously during the attempted synthesis of a branched oligogermane from Tol(3)GeNMe(2) and PhGeH(3). The mol-ecule contains an inversion center in the middle of the Ge(4)O(2) ring which is in a chair conformation. The Ge-Ge bond distance is 2.4418â (5)â Å and the Ge-O bond distances are 1.790â (2) and 1.785â (2)â Å. The torsion angles within the Ge(4)O(2) ring are -56.7â (1) and 56.1â (1)° for the Ge-Ge-O-Ge angles and -43.9â (1)° for the O-Ge-Ge-O angle.
