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.

Thiophene-2-carboxaldehyde (1.2 ml, 0.01 mol) was added to an ethanolic solution of nicotinicacid hydrazide (1.37 g, 0.01 mol). After the addition was complete, the reaction mixture was stirred thoroughly at 273 K. To this mixture concentrated hydrochloric acid (five drops) was added and stirred. The reaction mixture was kept at this temperature for 30 min. On completion of the reaction, the resulting solid mass was seperated, filtered, dried and washed with diethylether. A pale yellow solid was obtained that was recrystallized from ethanol [yield: 82%].
The H atoms of the solvent water molecules and of the hydrazide moiety were located in a difference map and were refined freely. All other H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with C—H = 0.93 Å, N—H = 0.86 Å and with Uiso(H) = 1.2Ueq(C, N).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |
