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

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.
