Value type “crystal system (Q898786)”: This property should use items as value that contain property “instance of (P31)”. On these, the value for instance of (P31) should be an item that uses subclass of (P279) with value crystal system (Q898786) (or a subclass thereof). (Help)

Specifying more specific crystal systems
[edit]Would this property be the right to use for noting the crystal structure of metals? For example copper (Q753) → face-centered cubic (Q3006714) (also making face-centered cubic (Q3006714) a subclass of cubic crystal system (Q473227). I think it would also make sense to make the relax the condition be subclass of crystal system (Q898786) regardless. Belteshassar (talk) 19:45, 1 June 2020 (UTC)
- You have crystal system, point group, space group and cell parameters. See albite and sodium chloride. Regards --Chris.urs-o (talk) 17:41, 12 September 2020 (UTC)
