Unit-cell angle alpha of the reported structure in degrees.
Unit-cell angle beta of the reported structure in degrees.
Unit-cell angle gamma of the reported structure in degrees.
The number of the formula units in the unit cell as specified by _chemical_formula.structural, _chemical_formula.moiety or _chemical_formula.sum.
Unit-cell length a corresponding to the structure reported in angstroms.
Unit-cell length b corresponding to the structure reported in angstroms.
Unit-cell length c corresponding to the structure reported in angstroms.
To further identify unique axis if necessary. E.g., P 21 with an unique C axis will have 'C' in this field.
Cell volume V in angstroms cubed.
V = a b c (1 - cos^2^alpha - cos^2^beta - cos^2^gamma
+ 2 cosalpha cosbeta cosgamma)^1/2^
a = _cell.length_a b = _cell.length_b c = _cell.length_c alpha = _cell.angle_alpha beta = _cell.angle_beta gamma = _cell.angle_gamma
