N'-[(E)-(4-Bromo-2-thien-yl)methyl-idene]benzohydrazide 0.06-hydrate.

ABSTRACT: The title compound, C(12)H(9)BrN(2)OS·0.06H(2)O, is a hydrated Schiff base derived from benzoic hydrazide and 4-bromo-thio-phene-2-carboxaldehide. The two Schiff base mol-ecules in the asymmetric unit differ crystallographically: in one mol-ecule the dihedral angle between the benzene ring and thio-phene ring is 49.88?(11)°, whereas the other mol-ecule the rings are almost coplanar with an r.m.s. deviation for the non-H atoms of 0.025?Å. In the crystal, mol-ecules form polymeric sheets linked by N-H?O and C-H?O hydrogen bonds. The water mol-ecule of crystallization is partially occupied and its H atoms could not be located.
