1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-aminium bromide monohydrate

摘要

In the title hydrated mol­ecular salt, C11H14N3O⁺·Br⁻·H2O, the Br⁻ anion is split and appears as two independent half-occupied Br⁻ anions on twofold rotation axes. The dihedral angle between the phenyl ring and the mean plane of the 2,3-dihydro-1H-pyrazole ring (r.m.s. devation = 0.014 Å) is 62.43 (7)°. In the crystal, the components are connected via O—H⋯Br and N—H⋯O hydrogen bonds to form a one-dimensional polymeric structure propagating along [001].
