The molecular conformation is stabilized by weak intramolecular C—H interactions. In the crystal, molecules are linked by O—H N hydrogen bonds, forming chains running parallel

The molecular structure is characterized by an intramolecular N—H O hydrogen bond, which generates an S (7) ring motif while an intermolecular N—H O hydrogen bond links

In the hydrogen malate anion, an intramolecular O—H O hydrogen bond generates an S(7) ring and results in a folded conformation.. In the crystal, the protonated N atom and

benzene ring. The conformation of the molecule is in part stabilized by an intramolecular O—H O hydrogen bond. In the crystal structure, molecules related through inversion

In the crystal structure, there is an intramolecular N—H N hydrogen bond forming a five-membered ring (Table 2) and also an intermolecular C—H O hydrogen bond between the O

The absence of disorder in the thiophene ring facilitates one of its ring C atoms to participate in the lone intermolecular C—H  O hydrogen bond present in the crystal, leading to

In the crystal, molecules related by a twofold rotation axis are linked via O—H  N hydrogen bonds involving the water molecule and a pair of C—H  N hydrogen bonds forming
