_cell_length_

Names

'_cell_length_a' '_cell_length_b' '_cell_length_c'

Category: cell

Data type: numb (with optional s.u. in parentheses)

Enumeration range: 0.0 -> infinity

Units: A ( angstroms)

Definition

    	
   Unit-cell lengths in angstroms corresponding to the structure
   reported. The values of _refln_index_h, *_k, *_l must
   correspond to the cell defined by these values and _cell_angle_
   values. The values of _diffrn_refln_index_h, *_k, *_l may not
   correspond to these values if a cell transformation took place
   following the measurement of diffraction intensities. See also
   _diffrn_reflns_transf_matrix_.
