Succinic acid has been known since 1546 and was first chemically identified in the mid‐19th century. In an attempt to prepare a molecular salt of succinic acid with ( S )‐(−)‐α‐methylbenzylamine, we have obtained the second polymorph of the monoammonium salt of succinic acid, NH 4 + ·C 4 H 5 O 4 − . The crystal structure determination proves the structure of the ionic compound and the intimate role of the ammonium ion in the structure, which is compared to the earlier described polymorph.
