An intramolecular ion‐pair interaction stabilizes the unusual, distorted coordination geometry of C 1 in 1 . In the course of the topomerization 1 ⇋ ent ‐ 1 , which was followed by NMR spectroscopy, the internal Zr ⃛CH 2 ion pair must be cleaved. The rearrangement pathway probably proceeds via a species with “normal” tetrahedral coordination geometry at C 1 .
