Hexadentate ligand

[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.

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

Example shapes are the tripod, and amplector, with a bifurcation at each end.

Rigid molecules can be used to force unusual coordination such as trigonal prism.
