Abstract

The crystal and molecular structuee of (+)450-cis-dichlorobis(ethylenediamine)platinum(IV) chloride, [Pt/C2H8N2)2Cl2]Cl2, has been determined from three-dimensional X-ray data collected by counter methods. The structure has been refined by least-squares techniques to a final R factor on F of 4.3% for 1564 reflections above background. The colorless crystals belong to space group C23-C2 of the monoclinic system. The cell constants are: a = 10.668 (14), b ±= 10.687 (13), c = 11.339 (14) Å, and β = 101.21 (2)°. The calculated density of 2.44 g/cm3 for four formula units in the unit cell agrees well with the observed density of 2.45 (1) g/cm3. The structure of the complex ion is that of a slightly distorted octahedron. The coordinated chlorines occupy cis positions. The average Pt-Cl distance is 2.306 (4) Å and the average Pt-N distance is 2.057 (6) Å. The absolute configuration of the complex is Λ, and the conformations of the two chelate rings are λλ.
