Molecular Kinder eggs are generated from N‐centered tripodal heptadentate tris(1,3‐diketonate) ions (L 3− ) in the presence of indium ions. The tetrahedral complexes host a cesium ion ([Cs⊂{In 4 (L) 4 }] + , see picture) or four protons. Deprotonation of the species [In 4 (H N L) 4 ] 4+ generates the empty cage compound [In 4 (L) 4 ], which comes with a break of the symmetry in the initial C 3 ‐symmetric tripodal ligand.
