Difluoroarylgroup was disordered over two-positions, with a refined occupation
of sites of 81:19.  The C6F2H3 fragments associated with C1A-C6A and C1B-C6B
were restrained to having similar geometry using the SAME command. Many of the
carbon atoms in this fragment are nearly overlapping, and thus the EADP command
was used to force the nearly ovelapping atoms to have similar thermal parameters.
