Abstract: | Preparation and Characterization of Pt(mal)2]2? and trans-Pt(mal)2X2]2? (X = Cl, Br, I, SCN) By twofold treatment of K2PtCl4] with potassium hydrogen malonate in a queous solution the yellow K2Pt(mal)2] · H2O is obtained. After extraction with tetrabutylammonium ions into dichloromethane by oxidative addition at ?90°C the PtIV complexes Pt(mal)2X2]2?, X = Cl, Br, I, SCN, are formed. The SCN ligands are coordinated to Pt via S. The IR and Raman spectra are discussed and assigned. |
