The triple ion formation from various ammonium or guanidium chlorides has been examined by conductometry in acetonitrile, benzonitrile, and propylene carbonate. The observed minimum in the Λ−C1/2 curve of diethylcyclohexylammonium chloride in benzonitrile could be reproduced in terms of a large formation constant of quadrupole complexes by computer simulations.
