In the anhydrous salt formed from the reaction of morpholine with cinnamic acid, C4H10NO+·C9H7O2−, the acid side chain in thetrans-cinnamate anion is significantly rotated out of the benzene plane [C—C—C— C torsion angle = 158.54 (17)°]. In the crystal, one of the the aminium H atoms is involved in an asymmetric three-centre cation–anion N—H...(O,O′)R12(4) hydrogen-bonding interaction with the two carboxylate O-atom acceptors of the anion. The second aminium-H atom forms an inter-species N—H...Ocarboxylatehydrogen bond. The result of the hydrogen bonding is the formation of a chain structure extending along [100]. Chains are linked by C—H...O interactions, forming a supramolecular layer parallel to (01-1).
