Formation of anionic σ-aryl complexes of platinum (IV) in the reaction of H2PtCl6 with aromatic compounds. The crystal and molecular structures of platinum (IV) complexes of naphthalene and ortho-nitrotoluene

The crystal and molecular structures of anionic platinum(IV) complexes of naphthalene (I) and ortho-nitrotoluene (II) have been determined by X-ray diffraction. The structures of both complexes are similar. The platinum atom is octahedrally coordinated with four chlorine atoms occupying the equatorial positions and σ-bonded aryl and neutral ammonia ligands situated in the axial positions.
