Symmetry dictionary (symCIF) version 1.0.1
_space_group.name_H-M_full
Name:'_space_group.name_H-M_full'
Definition:
The full international Hermann-Mauguin space-group symbol as defined in Section 2.2.3 and given as the second item of the second line of each of the space-group tables of Part 7 of International Tables for Crystallography Volume A (2002). Each component of the space-group name is separated by a space or an underscore character. 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. Subscripts should appear without special symbols. Bars should be given as negative signs before the numbers to which they apply. The commonly used Hermann-Mauguin symbol determines the space-group type uniquely but a given space-group type may be described by more than one Hermann-Mauguin symbol. The space-group type is best described using _space_group.IT_number or _space_group.name_Schoenflies. The full international Hermann-Mauguin symbol contains information about the choice of basis for monoclinic and orthorhombic space groups but does not give information about the choice of origin. To define the setting uniquely use _space_group.name_Hall, list the symmetry operations or generators, or give the transformation relating the setting used to the reference setting defined in this dictionary under _space_group.reference_setting.
