The structure has " P2 1 3 " space group symmetry at low temperatures.
2.
The order can consist either in a full crystalline space group symmetry, or in a correlation.
3.
:Precession electron diffraction enables much more direct determination of space group symmetries over other forms of electron diffraction.
4.
This image provides the investigator with information about the space group symmetries in the crystal and the crystal's orientation to the beam path.
5.
Specifically, the crystal's external morphological symmetry must conform to the angular components of the space group symmetry operations, without the translational components.
