The trigermanes Bu^tMe₂GeGePh₂GeMe₂Bu^t and PhMe₂GeGePh₂GeMe₂Ph and the tetragermanes Et₃Ge(GePh₂)₂GeEt₃ and Buⁿ₃Ge(GePh₂)₂GeBuⁿ₃ were synthesized via the hydrogermolysis reaction. These species were characterized by UV/visible spectroscopy, cyclic voltammetry, and differential pulse voltammetry. The properties of the two trigermanes were also compared with those of Buⁿ₃GeGePh₂GeBuⁿ₃, and the UV/visible absorption maxima of these three trigermanes fall in the narrow range of 246 – 249 nm while their oxidation potentials differ by 233 mV. Both Bu^tMe₂GeGePh₂GeMe₂Bu^t and Buⁿ₃GeGePh₂GeBuⁿ₃ exhibit two irreversible oxidation waves in their CVs and DPVs. The absorption maxima for the two tetragermanes are similar and their oxidation potentials differ by only 58 mV. The CV and DPV of Et₃Ge(GePh₂)₂GeEt₃ exhibits three irreversible oxidation waves while that of Buⁿ₃Ge(GePh₂)₂GeBuⁿ₃ contains only one. The X-ray crystal structure of Et₃Ge(GePh₂)₂GeEt₃ was determined and this represents a rare example of a tetragermane with alkyl substituents at the terminal germanium atoms.
