Bis(acetonitrile)palladium dichloride is the

coordination complex A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the ''coordination centre'', and a surrounding array of chemical bond, bound molecules or ions, that are in turn known as ' ...

with the formula PdCl₂(NCCH₃)₂. It is the adduct of two acetonitrile

ligand In coordination chemistry, a ligand is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's el ...

s with palladium(II) chloride. It is a yellow-brown solid that is soluble in organic solvents. The compound is a reagent and a catalyst for reactions that require soluble Pd(II). The compound is similar to bis(benzonitrile)palladium dichloride. It reacts with 1,5-cyclooctadiene to give dichloro(1,5-cyclooctadiene)palladium.
