Zur Morphologie organischer Kristalle mit zwei Molekülen in der asymmetrischen Einheit. Ein Beitrag zur Korrespondenz von Kristallstruktur und Habitus

It has been demonstrated in an earlier publication, that pseudosymmetry influences crystal tracht of organic crystals. The morphological lattice of structures with two independent molecules in the unit cell corresponds with the lattice of the centers between the two molecules. This can be pointed out with aid of “morphological extinction rules”.
