The conformation of the C!C!C!C backbone of the monotartrate anion is close to anti [torsion angle = 173.18 (17)<], which is supported by two intramolecular O!H...O hydrogen bonds. In the crystal, the components are linked by N!H!O and O!H!O hydrogen bonds, generating (001) sheets. %U http://scripts.iucr.org/cgi-bin/paper?S1600536811055759
