Regex pattern:
^[A-Z0-9\.]+$
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
