The title compound, C4H6N3O +·C6HCl2O4 -·H2O, is a monohydrate salt of chloranilic acid (2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone) with cytosine [4-aminopyrimidine- 2(1H)-one]. In the crystal structure, the cytosinium cation, the hydrogen chloranilate anion and the water molecule are held together through O-H⋯O, N-H⋯O, N-H⋯Cl and C-H⋯O hydrogen bonds, forming a molecular tape. The tapes are further linked by O-H⋯Cl and C-H⋯Cl hydrogen bonds, forming a three-dimensional hydrogen-bond network.
