  Adding "C3" to the value of the _chemical_formula_sum data item, since:

  1) 'C3 H18 Be2 F7 N9' is the formula computed from atomic coordinates and symetry;
  2) the _chemical_formula_structural specifies 3 carbon atoms in total;
  3) The compound is declared to be guanidinium salt, and guanidinium contains carbon.
