point group

noun Crystallography

Any of the 32 sets of symmetry operations which can be used to characterize three-dimensional lattices and are the basis of the system of crystal classes.It crystallizes in the hexagonal system; its point group is thought to be 6 / m 2 / m 2 / m, although there is debate on its structure and symmetry....

A new method was devised to deduce the orientation of the C 3 trimer axis with respect to the unit cell framework without any other input from the x-ray crystallographic analysis than the 222 point group of the unit cell.
When taking into account the point group of the cocrystals (222 corresponding to the orthorhombic space group), the squares of the direction cosines between all C 3 axes and (a, b, c) should be identical.
