Category CHEMICAL_CONN_ATOM

Definition:

   Data items in the _chemical_conn_atom_ and _chemical_conn_bond_
   categories record details about the two-dimensional (2D)
   chemical structure of the molecular species. They allow a 2D
   chemical diagram to be reconstructed for use in a publication or
   in a database search for structural and substructural
   relationships.

   The _chemical_conn_atom_ data items provide information about
   the chemical properties of the atoms in the structure. In cases
   where crystallographic and molecular symmetry elements coincide,
   they must also contain symmetry-generated atoms, so that the
   _chemical_conn_atom_ and _chemical_conn_bond_ data items will
   always describe a complete chemical entity.
