Περίληψη:
IR, 1H NMR and 13C NMR spectra of cis-Pt(S-EtCys)Cl2 have been analyzed and interpreted in favor of a structure which the ethyl-cysteine ligand coordinates through its S and N atoms. Additionally, the 1H and 13C NMR spectra show the existence of two diastereomers, differing in their absolute configuration at sulfur. These conclusions were confirmed by a single-crystal X-ray structure determination, which showed the presence of both diastereomers in the unit cell. Crystallographic details: cis-Pt(S-EtCys)Cl2 crystallizes in the monoclinic space group P21, with a = 8.336(6) Å, b = 10.997(8) Å, c = 15.097(9) Å, β = 120.76(3)°, Z = 4. FinalR factor = 0.054 for 1842 reflections. © 1982.
