    title: inchi chemical sublayer
    comments:
    - in the case of hydrates, the dot separates the formula of the compound from
      the water molecules. For example, CuSO₄·5H₂O represents copper(II) sulfate pentahydrate,
      indicating that there are five water molecules associated with each copper(II)
      sulfate unit in the crystal.
    - 'Salt Formulations: Dots can also be used to denote the proportions in which
      different components are combined to form a salt. For instance, "CaCl₂·2AgNO₃"
      would suggest a complex formed from one unit of calcium chloride and two units
      of silver nitrate, though this particular example is more illustrative than
      practical.'
    - 'Coordination Complexes: In coordination chemistry, dots can separate the metal
      complex from its counterions or ligands that are not directly bonded to the
      metal center. For example, "[Co(NH₃)₆]Cl₃" indicates a complex of cobalt with
      six ammonia ligands, and the three chloride ions are counterions. If written
      as "[Co(NH₃)₆]·3Cl", it would similarly denote the presence of three chloride
      ions associated with the complex, though this notation is less common'
    - 'Molecular Assemblies: For certain supramolecular structures or assemblies,
      dots might be used to indicate a non-covalent association of components. This
      usage is less common and more context-dependent'

  smiles_string:
    name: smiles_string
    description: A string encoding of a molecular graph, no chiral or isotopic information.
      There are usually a large number of valid SMILES which represent a given structure.
      For example, CCO, OCC and C(O)C all specify the structure of ethanol.
    title: smiles string
    comments:
    - a problematic set of structures to describe using SMILES notation is those which
      cannot be easily described using molecular graphs (see “Limitations of molecular
      graph representations” section), such as organometallic compounds and ionic
      salts.
