Abstract

Continuing the work started by previous members of the Williams group, two new compounds have been added to the bis-benzimidazoles family. These chiral compounds can form mononuclear and polynuclear complexes with transition metal ions. Depending on the reaction conditions, mononuclear species can be isolated in the solid state as part of a hydrogen bonded dimer. Measurement of the magnetic susceptibility showed that the metal ions, both in the polynuclear and in the dimeric species, are coupled ferro or antiferromagnetically. Studies on solution showed that the dimeric species can be formed and are stable in solution as well. The polynuclear species obtained are mainly heterocubanes. It was shown that the helicity of these heterocubanes depends on the ligand used: both its chirality and its degree of substitution have an influence on the final structure of the complex.
