'''Ammonium malate''' refers to ]s containing malate and ammonium. Two stoichiometries are discussed: NH<sub>4</sub>H(C<sub>2</sub>H<sub>3</sub>OH(CO<sub>2</sub>)<sub>2</sub>) with one ammonium ion per formula unit, and (NH<sub>4</sub>)<sub>2</sub>(C<sub>2</sub>H<sub>3</sub>OH(CO<sub>2</sub>)<sub>2</sub>). Malate, the conjugate base of ], is chiral. Consequently a variety of salts are possible, R vs S vs racemic. The monoammonium salt has been crystallized as the monohydrate.<ref>{{cite journal |doi=10.1016/j.jcrysgro.2007.12.024|title=Synthesis, crystal growth, structural, optical, thermal and mechanical properties of novel organic NLO material: Ammonium malate|year=2008|last1=Anandha Babu|first1=G.|last2=Bhagavannarayana|first2=G.|last3=Ramasamy|first3=P.|journal=Journal of Crystal Growth|volume=310|issue=6|pages=1228–1238|bibcode=2008JCrGr.310.1228A}}</ref> |
