Hexadentate ligand

A hexadentate ligand in coordination chemistry is a ligand that combines with a central metal atom with six bonds.[1] One example of a hexadentate ligand that can form complexes with soft metal ions is TPEN.[1] A commercially important hexadentate ligand is EDTA.

Generic structure of a metal complex of hexadentate EDTA.

The denticity of hexadentate ligands is often denoted with the prefix κ6.
