Abstract

We report on the synthesis of 11 pentameric cyclic helicates formed by imine condensation of alkyl monoamines with a common bis (formylpyridine) bipyridyl-derived building block and iron (II) and chloride ions. The cyclic double-stranded helicates were characterized by NMR spectroscopy, mass spectrometry, and in the case of a 2, 4-dimethoxybenzylamine- derived pentameric cyclic helicate, X-ray crystallography. The factors influencing the ...
