Dichloro(1,5-cyclooctadiene)platinum(II) (Pt(cod)Cl2) is an organometallic compound of platinum. This colourless solid is an entry point to other platinum compounds through the displacement of the cod and/or chloride ligands. It is one of several complexes of cycloocta-1,5-diene.
Dichloro(1,5-cyclooctadiene)platinum(II) is prepared by treating potassium tetrachloroplatinate with the diene:
K2PtCl4 + C8H12 → PtCl2C8H12 + 2 KCl
It can also be prepared by a mechanochemical method starting with PtCl2.
According to X-ray crystallography, the complex is square planar.
