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 Pt(IV)Me3 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 Pt(IV)Me3 salicylaldiminate 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.
