The longest wavelength absorption of the dark blue solution of the tetragermabutadiene 1
(Tip= 2, 4, 6‐iPr3C6H2) in n‐hexane at 560 nm indicates a pronounced conjugation of the
two Ge− Ge double bonds. In the crystal, 1 adopts the s‐cis conformation with a dihedral
angle for the Ge4 framework of 22.5°.
