Mono‐ and bimetallic cadmium(II) porphyrin complexes show dynamic behavior relying on a reversible metal‐to‐N‐core interaction. In the bimetallic complex, a rare coupled intraligand migration of the two cations, resembling the motion of spheres in a “two‐ball” Newton's cradle device, is triggered by acetate anions (allosteric control). The cations concomitantly switch between the strap and porphyrin binding sites, while staying on their respective side of the ligand. For more information see the Full Paper by S. Le Gac, B. Boitrel et al. on page 13376 ff.
