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 asymmetric unit 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.
