Adjective
polydentate (comparative more polydentate, superlative most polydentate)
(chemistry, of a ligand) Coordinated to the central atom by several bonds; multidentate
Ambidentate ligand main Unlike polydentate ligands, ambidentate ligands can attach to the central atom in two places. Source: Internet
A polydentate (multiple bonded) ligand is a molecule or ion that bonds to the central atom through several of the ligand's atoms; ligands with 2, 3, 4 or even 6 bonds to the central atom are common. Source: Internet
Spectator ligand main A spectator ligand is a tightly coordinating polydentate ligand that does not participate in chemical reactions but removes active sites on a metal. Source: Internet
The number of times a polydentate ligand binds to a metal centre is symbolized by "κ n ", where n indicates the number of sites by which a ligand attaches to a metal. Source: Internet
