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.
