Cover illustration: Constructor graph of (3,5-dimethyl-1H-pyrazol-4-ylmethyl)isopropylammonium chloride monohydrate, viewed along the a axis. Arrows denote five types of hydrogen bonds, originate at the donor molecules and point to acceptor molecules. Squares represent cations, triangles Cl^- anions and circles water molecules. Solid symbols are translated mirror images of the open symbols. See Guzei, Keter, Spencer & Darkwa [Acta Cryst. (2007), C63, o481-o483].
