Bis(creatininium) 3-nitrophthalate monohydrate

Abstract

In the title hydrated molecular salt, 2C4H8N3O+·C8H3NO62−·H2O, the dihedral angles between the benzene ring and the nitro group and the carboxylate groups are 48.0 (2), 55.3 (2) and 60.7 (2)°, respectively. In the crystal, the components are linked by N—H...O, O—H...O and C—H...O hydrogen bonds, generating a two-dimensional network parallel to (102).
