A framework distinguishing a central atom’s coordination sphere, ligand count, geometry, and counterions from simple valence formulas.

This is an authored directed relation from the source endpoint to the target endpoint.
Werner’s coordinated-versus-ionizable ligand distinctions and predicted isomer counts materially motivated acceptance of spatial coordination theory.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
wp-chem-wernernobel-werner-1913Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Coordination theory organizes central atoms, coordinated ligands, geometry, and outer-sphere ions.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
