Abstract: | On Polygermanes. II. Modifications of Dodecaphenylcyclohexagermane Dodecaphenylcyclohexagermane (1) can be obtained from solutions pure (1a) , with 2 und 7 moles of crystal benzene (1b, 1c) and with 2 moles of crystal toluene (1d). Mass spectrum, 13C-nmr spectrum, assigned vibrational spectra (vs, Ge? Ge? Ge = 220–235 cm?1, vas, Ge? Ge? Ge = 245–260 cm?1) and crystal data are given. The crystal structure of 1c has been determined and refined to a R of 0.059. 1 forms a flattened Ge6-chair (Ge-Ge distance 245.7(1) pm) with 6 axial and equatorial substituents respectively. The molecules of 1 approach spheres with a packing midway between a simple cubic and a cubic closest-packed arrangement. |
