N′(2),N′(5)-Bis[(E)-2-hy­droxy­benzyl­idene]-3,4-dimethyl­thio­phene-2,5-dicarbohydrazide

In the title mol­ecule, C(22)H(20)N(4)O(4)S, both C=N bonds are in an E conformation. The benzene rings form dihedral angles of 12.10 (13) and 25.17 (12)° with the thio­phene ring. The dihedral angle between the two benzene rings is 17.59 (14)°. There are two intra­molecular O—H⋯N hydrogen bonds. In...

Sumario:In the title mol­ecule, C(22)H(20)N(4)O(4)S, both C=N bonds are in an E conformation. The benzene rings form dihedral angles of 12.10 (13) and 25.17 (12)° with the thio­phene ring. The dihedral angle between the two benzene rings is 17.59 (14)°. There are two intra­molecular O—H⋯N hydrogen bonds. In the crystal, N—H⋯O hydrogen bonds connect mol­ecules into chains along [010].
