Summary
-
1.
The “barrier” character of the germanium atom in the vibration spectra of organogermanium molecules was established. The characteristic frequencies for the groups Cr3, C2H5, and n-C3H7 joined to Ge were found.
-
2.
A dependence between the frequency of the fully symmetric valence vibrations of the Ge-C bond and the effective electronegativity of the substituents on the germanium atom was established. A formula is given which expresses this dependence.
-
3.
It was found that (C2H5)4Ge analogously to (C2H5)4Si, can react with aluminum chloride at 160–180°.
