Resumo[Pt(dien)Cl]Cl (dien = diethylenetriamine) has been obtained in high yield ( > 90%) by interaction of cis-[Pt(dmso)2Cl2] (dmso = dimethylsulfoxide) with the triamine in methanol. The same method, when applied to 2,2′ : 6′,2″-terpyridine (terpy), gave a mixture of [Pt(terpy)Cl][Pt(dmso)Cl3] and [Pt(terpy)Cl]Cl·2H2O. The latter complex has been obtained in nearly quantitative yield by interaction of equimolar amounts of [Pt(COD)Cl2] (COD = 1,5-cyclooctadiene) and terpy in water.
