The title compound, C12H9BrN2OS·0.06H2O, is a hydrated Schiff base derived from benzoic hydrazide and 4-bromothiophene-2-carboxaldehide. The two Schiff base molecules in the differ crystallographically: in one molecule the dihedral angle between the benzene ring and thiophene ring is 49.88 (11)°, whereas the other molecule the rings are almost coplanar with an r.m.s. deviation for the non-H atoms of 0.025 Å. In the crystal, molecules form polymeric sheets linked by N—H⋯O and C—H⋯O hydrogen bonds. The water molecule of crystallization is partially occupied and its H atoms could not be located.

To a hot stirred solution of benzoic hydrazide (1.36 g, 0.01 mol) in ethanol (15 ml) was added 4-bromo-2-thiophencarboxaldehide (1.91 g, 0.01 mol). The resultant mixture was then heated under reflux. After an hour precipitates were formed. The reaction mixture was further heated about 30 min for the completion of the reaction which was monitored through TLC. The reaction mixture was cooled to room temperature, filtered and washed with hot ethanol. The crude material was recrystallized in hot methanol to affoard colourless needles of (I).
There exist solvent accessible volume if only two Schiff base molecules are refined. Therefore, the largest difference peak was taken as a water O-atom and refined anisotropically with an occupancy factor of 0.125. Its presumed H atoms could not be located.
The other H-atoms were positioned geometrically with N—H = 0.86, C—H = 0.93 Å for aromatic H atoms and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C, N).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

The title compound (I, Fig. 1), has been prepared for complexation with various metals and with hope that it will be biologically active as well. The biological studies of (I) are under progress.
The crystal structure of (I) differs from (II) (N'-2-(thienylidene))benzhydrazide (Aldoshin et al., 1991) due to bromo substitution.
The title compound consist of two crystallographically different molecules and fractional part of O-atom which occupies the solvent accessible area. The fractional O-atom may be part of methanol, ethanol or water from air. The molecules are stabilized in the form of polymeric sheets due to H-bondings (Table 1, Fig. 2) which extend along the c axis. In one molecule the benzene ring A (C1—C6) and the thiophene ring B (C9—C10, S1) are oriented at a dihedral angle of 49.88 (11)° whereas in the other molecule both rings are nearly planar with an r.m.s. deviation of 0.025 Å.
