_space_group.name_Hall
Name:'_space_group.name_Hall'
Definition:
Space-group symbol defined by Hall. Each component of the space-group name is separated by a space or an underscore. The use of a space is strongly recommended. The underscore is only retained because it was used in old CIFs. 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. Ref: Hall, S. R. (1981). Acta Cryst. A37, 517-525; erratum (1981), A37, 921. [See also International Tables for Crystallography Vol. B (2001), Chapter 1.4, Appendix 1.4.2.]Examples:
