2-Amino-3-methyl-pyridinium 2-amino-5-methyl-pyridinium sulfate monohydrate.

ABSTRACT: The asymmetric unit of the title compound, 2C(6)H(9)N(2) (+)·SO(4) (2-)·H(2)O, contains two isomeric protonated amino-methyl-pyridine cations, a sulfate anion and a solvent water mol-ecule. The cations are in the iminium tautomeric form. In the crystal structure, inter-molecular O-H?O, N-H?O and weak C-H?O hydrogen bonds link the components into a three-dimensional network. Additional stabilization is provided by weak ?-? stacking inter-actions, with centroid-centroid distances of 3.758?(2) and 3.774?(1)?Å.
