چکیده
The title compound, C(12)H(14)N(5)O(2) (+)·Br(-), is the hydro-bromide salt of a Schiff base in which protonation has taken place at the pyridine N atom. This organic cation is essentially planar (r.m.s. of all fitted non-H atoms = 0.0448 Å). In the crystal, N-H⋯Br hydrogen bonds as well as C-H⋯O and C-H⋯Br inter-actions connect the mol-ecules, forming a three-dimensional network.

The title compound, C19H19N5O5·3.5H2O, crystallizes with 3.5 mol-ecules of water in the asymmetric unit, one of which lies on a mirror plane. One of the water mol-ecules links the mol-ecules, forming centrosymmetric dimers. These dimers are then linked through further N-H⋯O and O-H⋯O hydrogen bonding, leading to the observed three-dimensional structure.
