Abstract
The reactivity of the cyclic primary aliphatic amines cyclopropyl-, cyclopentyl-and cyclohexylamine with cis- and trans-[PtCl(2)(NCMe)(2)], under the same experimental conditions, is compared. Whereas cis-[PtCl(2)(NCMe)(2)] yields the neutral diamidine compounds, the reactions with trans-[PtCl(2)(NCMe)(2)] take place either with addition or substitution processes yielding the neutral diamidine complexes trans-[PtCl(2)(Amidine)(2)], the monocationic trans-[PtCl(Amine)(Amidine)(2)]Cl and the dicationic trans-[Pt(Amine)(2)(Amidine)(2)]Cl(2) 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 trans-[PtCl(2){N(H)=C(CH(3))NHCHCH(2)CH(2)}(2)] is reported and its supramolecular arrangement is described. (C) 2009 Elsevier B. V.
