 Marking atoms 'C12a', 'H12a', 'H12b' and 'C12b', 'H12c', 'H12d' as
 belonging to disorder sites '1' and '2' accordingly.

 Changing the _atom_site_fract_z data item value from '-0.121' to
 '0.121' for atom 'H12d' after consulting the original publication.
 Hydrogen atom coordinates are not explicitly given in the paper,
 but it is noted that they are all included at the geometrically
 idealized positions (0.97 \%A). The coordinate change puts atom 'H(241)'
 at the 0.97 \%A distance from atom 'C12b' which was previously missing a
 hydrogen atom.

 Antanas Vaitkus,

 Changing the _atom_site_occupancy data item value from '?' to '1'
 for all fully occupied atom sites. The occupancies for atoms
 'H12a', 'H12b' and 'H12c', 'H12d' were determined from the occupancies
 of atoms they are attached to (atoms 'C12a' and 'C12b' respectively).
