_atom_sites.fract_transf_matrix[3][3]

Definition:

   The [3][3] element of the 3x3 matrix used to transform Cartesian
   coordinates in the ATOM_SITE category to fractional coordinates
   in the same category. The axial alignments of this
   transformation are described in _atom_sites.Cartn_transform_axes.
   The 3x1 translation is defined in
   _atom_sites.fract_transf_vector[].
