Abstract
Crystallization of N-chlorosaccharin with quinuclidine (QN) produced QN-Cl+ cations showing a covalent bond between chlorine and a tertiary nitrogen atom. Strong (supramolecular) halogen bonds between the QN-Cl+ and Cl− anions in their 2 : 1 and 1 : 1 complexes comprise a large contribution of orbital (covalent) interactions.
