Аннотация:A statistical analysis of the distribution of crystal structures of 6006 minerals across syngonies, symmetry classes, and space groups is presented. Significant changes relative to similar datasets from the early 21st century have been identified. It is shown that all 32 symmetry classes are fully occupied by mineral structures. The number of unoccupied space groups in structural mineralogy has decreased to 34. This study demonstrates for the first time that all symmetry space groups are fully occupied by inorganic crystals.
