Organometallic chemistry

A tridentate ligand clamps a metal centre

In organometallic chemistry, a pincer is a rigid tridentate ligand that binds a metal centre through three donor atoms arranged in a line, gripping it like a clamp and giving the resulting complex marked thermal stability and distinctive reactivity. Moulton and Shaw's 1976 report of tridentate bis(phosphinomethyl)phenyl complexes of nickel, palladium, platinum, rhodium, and iridium established the first examples of what became the pincer-complex family. The referent is a tridentate chelating framework and its metal complex, sharing only the clamping image with a battlefield encirclement or an animal's claw.[1]

Unit
The tridentate coordination geometry by which the ligand clamps a metal centre
Recovery means
Not applicable
Measured by
Characterised by coordination geometry, metal–donor bonding, and the stability and reactivity of the complex
