  Added moiety chemical formula from Marsh (1997) paper. The summary
  chemical formula is calculated from moiety formula using 'AdHocParser'
  (svn://www.crystallography.net/cod-tools/trunk/Formulae/AdHocParser.yp,
  revision 1441.)

  Removing 15 atoms which were symmetric equivalents of the atoms from
  the asymmetric unit.
