Modulated structures dictionary (msCIF) version 3.2.1

_space_group.ssg_name

Definition:

   

      Superspace-group symbol conforming to an alternative definition
      from that given in _space_group_ssg_name_IT and
      _space_group_ssg_name_WJJ for one-dimensional modulated
      structures or to the superspace-group name for higher dimensions.
      When necessary, indicate the origin and the setting. Use a colon
      ':' as a separator between the different parts of the
      superspace-group symbol. Within each part, leave a space
      between each component. Rules for the notation for
      Hermann-Mauguin and Hall symbols (if present) are given in the
      symmetry CIF dictionary (cif_sym.dic) and, partially, in
      _space_group_ssg_name_IT and _space_group_ssg_name_WJJ.
      For composites described in a single data block, the superspace
      group describes the symmetry of the whole structure. The
      symmetry of each subsystem can be derived using the
      appropriate W matrices.
