Coordination Compounds

Werner proposed that metals in coordination

Werner proposed that metals in coordination compounds show primary valence and secondary valence. Primary valence is ionisable and is satisfied by neg

A coordination entity is a central

A coordination entity is a central metal atom or ion bonded to a fixed number of ligands. The species inside square brackets forms the coordination sp

Ligands are ions or molecules attached

Ligands are ions or molecules attached to the central metal atom or ion. They may be unidentate, didentate, polydentate, chelate, or ambidentate. EDTA

Coordination number is the number

Coordination number is the number of ligand donor atoms directly bonded to the metal through sigma bonds. Common coordination polyhedra are octahedral

In naming coordination compounds

In naming coordination compounds, ligands are written before the metal name in alphabetical order, oxidation state is shown in Roman numerals, and ani
