A new bis(salicylimine) ligand based on the Tröger's base scaffold was synthesized in racemic and enantiomerically pure form. Upon coordination to zinc(II) ions this ligand undergoes highly diastereoselective self‐assembly into neutral dinuclear double‐stranded helicates as proven by XRD analysis and via comparison of experimental ECD spectra with those simulated with quantum‐chemical methods. When the racemic ligand was used, self‐assembly occurs under narcissistic self‐sorting resulting in the formation of a racemic pair of helicates as revealed by NMR spectroscopy and XRD analysis.
