A bidentate leaf has two distinct notches along its edge.

Definition

1. Adjective:
   • Having two teeth or toothlike projections: In biology and chemistry, "bidentate" describes a structure that has two points of attachment or two tooth-like parts.
   • Specifically in chemistry: Refers to a ligand that bonds to a central metal atom or ion at two points.

Usage Examples

• Adjective:
  • The molecule acts as a bidentate ligand, forming two coordinate bonds with the metal center.
  • Some leaves have a bidentate margin, with each tooth having a smaller notch.

Advanced Usage

• In coordination chemistry: A bidentate ligand, such as ethylenediamine (en), uses two donor atoms to bind to a single metal ion, forming a chelate ring. This increases the stability of the complex compared to a complex formed with two separate monodentate ligands.

Variants and Related Words

• Bidentate ligand (n): A specific type of ligand in chemistry that attaches via two atoms.
• Bidentately (adv): In a bidentate manner.
• Multidentate (adj): Having multiple (more than two) points of attachment (e.g., tridentate, tetradentate).

Synonyms

• Two-toothed
• Double-toothed
• Chelating (when specifically referring to ligands that form ring structures via multiple bonds)

Antonyms

• Monodentate (adj): Having only one point of attachment (in chemistry).
• Edentate (adj): Lacking teeth.

Related Phrases/Compounds

• Bidentate complex: A coordination compound featuring a bidentate ligand.
• Bidentate coordination: The mode of bonding where a ligand binds through two sites.
