groups on the tertiary amines. So, the π-electrons of the CC double bond are more available than the electron lone pair of nitrogen atom from the amino groups. When the π-electrons of the CC from the molecule of ligand were made unavailable by transforming the cyclohexene subunit into a benzene aromatic ring, no cis-diamino dichloroplatinum(II) complex nor trichloroplatinum-complexes were isolated but the

platinum(II) pi-olefin complex instead of the conventional square-planar cis Pt(II) coordination complex with the diamino ligand. This behavior was interpreted on the basis of the steric hindrance of the dimethylamino groups whose electron lone pairs are barely accessible to a platinum atom, which can make it difficult for both dimethylamino groups to bind platinum at the same time. This complex has been physically
