چکیده
In the cation of the title compound, C(16)H(14)N(3) (+)·Cl(-)·2H(2)O, the cyclo-hexa-1,3-diene ring displays a screw-boat conformation and the pyridine ring is slightly twisted with respect to the pyrazole ring with a dihedral angle of 4.56 (12)°. In the crystal, ions and water mol-ecules are linked into a three-dimensional network by classical N-H⋯O, N-H⋯Cl, O-H⋯Cl and O-H⋯O hydrogen bonds and by π-π stacking inter-actions, with centroid-centroid distances of 3.7580 (14) and 3.7794 (14) Å.
