2-Amino-5-iodopyridinium bromide hemihydrate and 2-amino-5-iodopyridinium chloride monohydrate

M. Polson, M. M. Turnbull and J. L. Wikaira

Synopsis: The title hydrate salts exhibit similar hydrogen bonding and [pi]-stacking in their crystal structures. The most interesting feature of the hydrochloride salt is the presence of an additional fractional HCl molecule which introduces disorder in the location of the water molecule.

Formula: C5H6IN2+·Br-·0.5H2O and C5H6IN2+·Cl-·H2O·0.375HCl
