General information
Spacegroup name _symmetry.space_group_name_H-M	P 21 21 21 Hermann-Mauguin space-group symbol. Note that the Hermann-Mauguin symbol does not necessarily contain complete information about the symmetry and the space-group origin. If used, always supply the FULL symbol from International Tables for Crystallography Vol. A (2002) and indicate the origin and the setting if it is not implicit. If there is any doubt that the equivalent positions can be uniquely deduced from this symbol, specify the _symmetry_equiv.pos_as_xyz or _symmetry.space_group_name_Hall data items as well. Leave spaces between symbols referring to different axes.
Unit cell parameters _cell.length_{a,b,c} _cell.angle_{alpha,beta,gamma}	51.035 Unit-cell length a corresponding to the structure reported in angstroms. 62.842 Unit-cell length b corresponding to the structure reported in angstroms. 69.057 Unit-cell length c corresponding to the structure reported in angstroms. 90.0 Unit-cell angle alpha of the reported structure in degrees. 90.0 Unit-cell angle beta of the reported structure in degrees. 90.0 Unit-cell angle gamma of the reported structure in degrees.
Wavelength _diffrn_radiation_wavelength.wavelength	NA

Data quality metrics	Overall
Low resolution limit [Å] _reflns.d_resolution_low	25.000 The largest value in angstroms for the interplanar spacings for the reflection data. This is called the lowest resolution.
High resolution limit [Å] _reflns.d_resolution_high	1.480 The smallest value in angstroms for the interplanar spacings for the reflection data. This is called the highest resolution.

Total number of observations	-
Total number unique _reflns.number_obs	32536 The number of reflections in the REFLN list (not the DIFFRN_REFLN list) classified as observed (see _reflns.observed_criterion). This number may contain Friedel-equivalent reflections according to the nature of the structure and the procedures used.
<I/σ(I)>	-
Completeness [%] _reflns.percent_possible_obs	86.2 The percentage of geometrically possible reflections represented by reflections that satisfy the resolution limits established by _reflns.d_resolution_high and _reflns.d_resolution_low and the observation limit established by _reflns.observed_criterion.
