An As2L3 metallocryptand is the result of a new predictive design strategy for forming self-assembled supramolecular arsenic complexes. The assembly is remarkably stable to a variety of competing metal ions, harsh acid, and excess ligand. X-ray crystallographic studies and density functional calculations suggest that a strong arsenic–π interaction adds stability to the structure.
