Preparation of Ternary Platinum(II) Complexes with N-(ω-Phenylalkyl)-1,2-ethanediamine and 2,2′-Dipyridine and the Effect of the Methylene Chain Length of the N-(ω-Phenylalkyl)-1,2-ethanediamine in the Complexes on Intermolecular Interactions with Various Arylsulfonates

Abstract

A series of ternary complexes comprised of platinum(II), 2,2′-dipyridine, and N-(ω-phenylalkyl)-1,2-ethanediamine was prepared by varying the number (n) of methylene chain carbons between the phenyl group and one of the amino groups of 1,2-ethanediamine. NMR measurements indicated that intramolecular stacking occurred for n=1 and intermolecular stacking occurred for n=3 for several of the aryl sulfonates.
