Modulated and composite structures dictionary (msCIF) version 1.0.1
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.Example:
