The series of oligogermanes Pri3Ge(GePh2)nGePri3 (n = 0, 2; n = 1, 3; n = 2, 4; n = 3, 5) were prepared by the hydrogermolysis reaction. All four species were characterized by NMR (1H and 13C) and UV/visible spectroscopy as well by cyclic voltammetry and differential pulse voltammetry. The oligogermanes exhibited a successive red shift in their absorbance maxima as the length of the Ge-Ge chain was increased, and these molecules also became easier to oxidize as the chain length was increased. The X-ray crystal structures of 4 and 5 as well as the trigermane HPh2GeGePh2GePh2H (6) were determined. The pentagermane 5 was shown to be dichroic in the solid state due to the packing of the individual molecules in a columnar fashion in the crystal. Pentagermane 5 is also luminescent in solution, exhibiting an emission maximum at 380 nm. The physical properties of 5, like the hexagermane Pri3Ge(GePh)4GePri3, mimic the properties of the larger polygermane systems.
