Ring stacking and laddering in ammonium carboxylate salts: extension to secondary ammonium salts

Abstract

An analysis of the crystal structures of secondary ammonium carboxylate salts using the ring stacking and laddering principle has been carried out. A Cambridge Structural Database analysis showed that this ionic model is applicable to the structures of these salts, and gives additional insight into their structural motifs. The crystal structures of seven new secondary ammonium carboxylate salts are reported, and analysed in terms of ring stacking and laddering.
