Innovative Tools for Teaching Crystallographic Symmetry: The Jmol Space Group Symmetry Visualizer

What is it about?

This paper introduces an online resource called the Jmol Space Group Symmetry Visualizer for visualizing crystallographic symmetry. This resource offers interactive pages for visualizing symmetry groups, including space groups, plane groups, and subperiodic groups such as frieze, rod, and layer groups. The visualization of these groups is enhanced through selected molecular and ionic structures, with color-coded symmetry elements that can be selectively displayed. Wyckoff positions are presented in tabular form, allowing for interactive manipulation while maintaining symmetry relationships. The website also lists atoms by Wyckoff positions, which can be labeled and colored by element, Wyckoff, or site symmetry. Maximal subgroups for all space groups are provided, facilitating the generation of group-subgroup relationship representations. This comprehensive set of tools is designed for students, educators, and researchers in crystallography, providing a flexible and modular approach to understanding crystallographic symmetry.
