Metal-phosphine complex
open-in-new
<p>A metal-phosphine complex is a <a href="/facts/Coordination_complex/1tCyeQUm">coordination complex</a> containing one or more phosphine ligands. Almost always, the phosphine is an <a href="/facts/Organophosphine/kNgIF93U">organophosphine</a> of the type R3P (R = alkyl, aryl). Metal phosphine complexes are useful in <a href="/facts/Homogeneous_catalysis/c7wplnb2">homogeneous catalysis</a>. Prominent examples of metal phosphine complexes include <a href="/facts/Wilkinson%2527s_catalyst/c7lrFXfo">Wilkinson's catalyst</a> (Rh(PPh3)3Cl), <a href="/facts/Grubbs%2527_catalyst/JtoGr3Qv">Grubbs' catalyst</a>, and <a href="/facts/Tetrakis(triphenylphosphine)palladium(0)/yg2ACYj6">tetrakis(triphenylphosphine)palladium(0)</a>. </p>
