Category:Crystals in space group 152 or 154

This is a non-diffusing subcategory of Category:Trigonal crystals. It includes crystals that can also be found in the parent category, or in diffusing subcategories of the parent.

This category lists crystals that display the symmetry of the P3₁21 space group (No. 152) of the trigonal crystal system, or the enantiomorphic space group P3₂21 (No. 154). The element or compound can assume either one of these two space groups.

The crystal being referred to may be just one of the possible forms of a named element or compound.
