Item Description

Space group symbol defined by Hall (Acta Cryst. (1981) A37, 517-525) (See also International Tables for Crystallography Vol.B (1993) 1.4 Appendix B). Each component of the space group name is separated by a space or an underscore. The use of space is strongly recommended. The underscore is only retained because it was used in earlier archived files. It should not be used in new CIFs. _space_group.name_Hall uniquely defines the space group and its reference to a particular coordinate system.
