Item Description

The Short International Hermann-Mauguin space group symbol as defined in Section 2.3 and given as the first item of each Space Group Table in Section 7 of International Tables for Crystallography Vol.A (1995). 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. Subscripts should appear without special symbols. Bars should be given as negative signs before the numbers to which they apply. The Short International Hermann-Mauguin symbol determines the space group type uniquely. However, the space group type is better described using the *.IT_number or *.name_Schoenflies. The Short International Hermann-Mauguin symbol contains no information on the choice of basis or origin. To define the setting uniquely use *.name_Hall, list the symmetry operations or generators, or give the transformation that relates the setting to the reference setting defined in this dictionary under *.reference_setting. _space_group.name_H-M_alt may be used to give the Hermann- Mauguin symbol corresponding to the setting used.
