Structure information from morphological data of organic crystals with the help of Patterson methods

Abstract

AbstractThe morphological points of a space group are special or general point configurations, respectively combinations of point configurations. There are mainly point configurations to be found, which in three‐dimensional space or at least in one projection, posses a higher translational symmetry than the crystallographic ones. The morphological lattice of organic structures with one molecule in the asymmetric unit e. g. corresponds to the lattice of the centers of gravity of molecules. Starting from the faces appearing on crystal, a possibility for deriving structure information with the help of Patterson methods will be demonstrated.
