A molecular or ionic entity containing a central atom bonded to a surrounding set of ligands.

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.

Crystal-field theory predicts geometry-dependent d-orbital splitting while neglecting explicit covalent bonding.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

Many coordination compounds are conventionally inorganic, with boundaries extending into organometallic and bioinorganic chemistry.
The target is a member or subtype of the broader source class.

Metal–ligand coordination can be described as Lewis-acid acceptance of ligand electron-pair density, while full bonding may include covalency and back-donation.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

Ligands are structural constituents of a coordination entity and can bind through one or several donor atoms.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Metal–ligand interactions determine geometry, electronic states, spectra, lability, and reactivity.
The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.

Coordination complexes are central entities in transition-metal chemistry but also occur for main-group and f-block centers.
The target is a member or subtype of the broader source class.

This is an authored directed relation from the source endpoint to the target endpoint.
Coordination number is assigned to a complex using a stated neighbor or donor-atom counting convention.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-inorganic-chemistryiupac-red-bookiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
A coordination complex can undergo ligand substitution when a leaving ligand and an entering ligand participate through a stated mechanism; lability, solvent, steric environment, and electronic structure affect the observed rate.
A physical process transforms the source into, or produces, the target under the conditions stated in the edge detail.

Idealized and distorted coordination geometries can be classified by molecular symmetry, constraining orbitals, spectra, and isomerism.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-inorganic-chemistryiupac-red-bookiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
A coordination complex can be assigned formal oxidation states by an explicit ionic approximation; noninnocent ligands, delocalization, and metal–ligand covalency can make localization ambiguous.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Many radiopharmaceuticals use chelators to control radionuclide speciation, targeting, kinetic stability, and in vivo distribution.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

VSEPR can provide a limited qualitative geometry model for some coordination environments, but ligand-field, steric, covalent, electronic, and relativistic effects often dominate transition-metal complexes.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.
