N,N-Diethyl-2-hydroxyethanaminium 5-(5-chloro-2,4-dinitrophenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-olate hemihydrate

The asymmetric unit of the title salt, C6H16NO+·C10H4ClN4O7−·0.5H2O, contains two cations, two anions and one water molecule. In one independent anion, one nitro group is rotationally disordered over two orientations in a 0.657 (8):0.343 (8) ratio. In the crystal, intermolecular N—H...O and O—H...O hydrogen bonds link all the components into ribbons extending along [100]
