The following rules apply to the construction of the data items _chemical_formula.analytical, _chemical_formula.structural and _chemical_formula.sum. For the data item _chemical_formula.moiety, the formula construction is broken up into residues or moieties, i.e. groups of atoms that form a molecular unit or molecular ion. The rules given below apply within each moiety but different requirements apply to the way that moieties are connected (see _chemical_formula.moiety). (1) Only recognized element symbols may be used. (2) Each element symbol is followed by a 'count' number. A count of '1' may be omitted. (3) A space or parenthesis must separate each cluster of (element symbol + count). (4) Where a group of elements is enclosed in parentheses, the multiplier for the group must follow the closing parenthesis. That is, all element and group multipliers are assumed to be printed as subscripted numbers. (An exception to this rule exists for _chemical_formula.moiety formulae where pre- and post-multipliers are permitted for molecular units.) (5) Unless the elements are ordered in a manner that corresponds to their chemical structure, as in _chemical_formula.structural, the order of the elements within any group or moiety should be: C, then H, then the other elements in alphabetical order of their symbol. This is the 'Hill' system used by Chemical Abstracts.

ENTITY data items describe the chemistry of the molecules under investigation and can most usefully be thought of as the ideal groups to which the structure is restrained or constrained during refinement. It is also important to remember that entities do not correspond directly to the enumeration of the contents of the asymmetric unit.
