| Abstract: | The reactivity of the cyclic primary aliphatic amines cyclopropyl-, cyclopentyl- and cyclohexylamine with cis- and trans-[PtCl2(NCMe)2], under the same experimental conditions, is compared. Whereas cis-[PtCl2(NCMe)2] yields the neutral diamidine compounds, the reactions with trans-[PtCl2(NCMe)2] take place either with addition or substitution processes yielding the neutral diamidine complexes trans-[PtCl2(Amidine)2], the monocationic trans-[PtCl(Amine)(Amidine)2]Cl and the dicationic trans-[Pt(Amine)2(Amidine)2]Cl2 salts. An NMR and ESI study indicate that the main species formed is the monocationic trans-[PtCl(Amine)(Amidine)2]Cl complex.The X-ray structure of  is reported and its supramolecular arrangement is described. |
