Item _chemical_formula.structural

Description

              See the CHEMICAL_FORMULA category description for the rules for
               writing chemical formulae for inorganics, organometallics, metal
               complexes etc., in which bonded groups are preserved as
               discrete entities within parentheses, with post-multipliers as
               required. The order of the elements should give as much
               information as possible about the chemical structure.
               Parentheses may be used and nested as required. This formula
               should correspond to the structure as actually reported, i.e.
               trace elements not included in atom type and atom site data
               should not be included in this formula (see also
               _chemical_formula.analytical).
