Platinum(II) acetate is a purple-colored coordination complex. The complex adopts an unusual structure consisting of a square array of Pt atoms.
Several syntheses of platinum(II) acetate have been reported. Geoffrey Wilkinson et al. reported a synthesis from sodium hexahydroxyplatinate, nitric acid, and acetic acid. This intermediate solution was reducted with formic acid. The procedure is not highly reproducible. [2]
Alternatively, the complex can be prepared by the reaction of silver acetate with platinum(II) chloride. [3]
According to X-ray crystallography, the complex is tetrameric, in contrast to the trimeric palladium analog. [4] The four platinum atoms form a square cluster, with eight bridging acetate ligands surrounding them. The compound has slight distortions from idealized D2d symmetry. The crystal is tetragonal.
