N′-[(E)-(4-Bromo-2-thien­yl)methyl­idene]benzohydrazide 0.06-hydrate

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-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 thio­...

description 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-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.
