Crystal structure of 8-hy­droxy­quinolin­ium 2-carboxy-6-nitro­benzoate mono­hydrate

In the title hydrated salt, C(9)H(8)NO(+)·C(8)H(4)NO(6) (−)·H(2)O, the deprotonated carboxyl­ate group is almost normal to its attached benzene ring [dihedral angle = 83.56 (8)°], whereas the protonated carboxyl­ate group is close to parallel [dihedral angle = 24.56 (9)°]. In the crystal, the compon...

Descripción
Sumario:In the title hydrated salt, C(9)H(8)NO(+)·C(8)H(4)NO(6) (−)·H(2)O, the deprotonated carboxyl­ate group is almost normal to its attached benzene ring [dihedral angle = 83.56 (8)°], whereas the protonated carboxyl­ate group is close to parallel [dihedral angle = 24.56 (9)°]. In the crystal, the components are linked by N—H⋯O and O—H⋯O hydrogen bonds, generating [001] chains. The packing is consolidated by C—H⋯O and π–π [centroid-to-centroid distances = 3.6408 (9) and 3.6507 (9) Å] inter­actions, which result in a three-dimensional network.
