Dichloro(cycloocta-1,5-diene)platinum(II) explained

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:^[1]

K₂PtCl₄ + C₈H₁₂ → PtCl₂C₈H₁₂ + 2 KCl

According to X-ray crystallography, the complex is square planar.^{[2] [3]}
