Abstract: The structure of the title compound, C7H11BrN2O·H2O, exhibits an elaborate hydrogen-bonding network involving pyrazole N-HO dimers and two other hydrogen-bonding motifs, both including water molecules. One motif is a distorted hexagonal R35(11) graph set, while the other is a distorted octagonal boat conformation R64(14) graph set.
