Tris(dibenzylideneacetone)dipalladium(0) or [Pd2(dba)3] is an organopalladium compound. The compound is a complex of palladium(0) with dibenzylideneacetone (dba). It is a dark-purplebrown solid which is modestly soluble in organic solvents. Because the dba ligands are easily displaced the complex is used as a homogeneous catalyst in organic synthesis.
