Solid-State Self-Assembly of Triazolylpyridine-Based Helicates and Mesocate: Control of the Metal–Metal Distances

Many materials properties are conditioned by the relative
arrangement
of metal ions in the solid state. Supramolecular architectures such
as helicates may be designed with controlled metal to metal spacing
in their midst. However, shorter distances and more extensive electronic
communication may be achieved between individual architectures through
their self-assembly in the solid state. In this manuscript, we report
a rational analysis of the solid-state self-organization of dinuclear
metallocylinders constructed by octahedral ion coordination with the
1,2,3-triazol-4-ylpyridyl chelate (FeII, NiII). Overall, aromatic and aliphatic spacers control the range and
ranking of metal to metal distances in a predictive manner.
