| Abstract: | The Schiff base ligands I–V, made by condensing either 2-acetylpyridine (I), 8-quinolinecarboxaldehyde (II and III), or o-methylthiobenzaldehyde (IV and V) with either N,N′-dimethyl-1,3-diaminopropane (I, II, and IV), 2-aminomethylpyridine (III), or 2-(2-aminoethyl)-pyridine (V), give ionic PtIVMe3 complexes containing tridentate NNN- or SNN-bonded ligands. With PtMe3Br ligand V gives a neutral complex XI in which it is coordinated only via the two N atoms. A monomeric PtIVMe3 salicyladiminate complex results on treating the dimeric trimethylplatinum(IV) salicylaldehyde complex with the bidentate amine H2N (CH2)3NMe2. The complexes have been fully characterised by 1H NMR spectroscopy. |
