Germanium(ll)phthalocyanine forms crystals belonging to space group P2/c with a=27.11, sigma=0.012 Å, b=10.39, sigma=0.020 Å, c=21.96, sigma=0.014 Å, beta=107.86, sigma-0.0680. There are eight molecules per unit cell.Patterson maps show that the molecule is planar, that the molecular axis is inclined 500 to the b axis, and that molecules are located parallel to each other along the b axis with an interplanar distance of 3.9 Å.
