Constructor graph description of hydrogen bonding in a supramolecular assembly of (3,5-dimethyl-1H-pyrazol-4-ylmethyl)isopropylammonium chloride monohydrate.

Five distinct strong hydrogen-bonding interactions of four kinds (N-H...Cl, N-H...O, O-H...N, and O-H...Cl) connect molecules of the title compound, C(9)H(18)N(3)(+).Cl(-).H(2)O, in the crystal structure into corrugated sheets stacked along the a axis. The intermolecular interactions are efficiently described in terms of the first- through fifth-level graph sets. A two-dimensional constructor graph helps visualize the supramolecular assembly.
