Noncovalent Interactions in Organometallic Compounds: Formation of an Intramolecular Metal–Carbon Ion Pair in Zirconium Borate Betaines

Abstract

The type of intramolecular stabilization of zirconium borate betaines is governed by the location of the substituents in the allyl unit: E configuration results in ZrF coordination (1), whereas Z configuration favors the formation of an internal ZrCH2[B] ion pair (2).
