Crystal structure of 3-({[(thiophen-2-yl)methylidene]hydrazinyl}carbonyl)pyridinium chloride dihydrate

Abstract

In the title compound, C11H10N3OS+·Cl−·2H2O, the organic cation exhibits a dihedral angle of 21.26 (8)° between the mean planes of the pyridine and thiophene rings, and dihedral angles of 15.11 (9) and 6.49 (9)° between the mean planes of the hydrazide moiety and the pyridine and thiophene rings, respectively. In the crystal, the organic cation, the chloride counter-anion and the two water molecules of crystallization are linked through an intricate hydrogen-bonding network consisting of O—H...O, O—H...N, N—H...Cl, C—H...Cl, C—H...O, N—H...O, O—H...Cl and C—H...S interactions that consolidate a three-dimensional network.
