3-Hydroxy­pyridinium hydrogen chloranilate monohydrate

Abstract

In the title salt hydrate, C5H6NO+·C6HCl2O4 −·H2O, the three components are held together by O—H⋯O and N—H⋯O hydrogen bonds, as well as by C—H⋯O contacts, forming a double-tape structure along the c axis. Within each tape, the pyridinium ring and the chloranilate ring are almost coplanar, forming a dihedral angle of 2.35 (7)°
