چکیده
In the title mol-ecule, C(12)H(10)N(2)O(3), the aromatic and furan rings form a dihedral angle of 8.89 (1)° and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into zigzag chains running along the c axis.

متن کاملN′-[(E)-Furan-2-ylmethylidene]-4-hydroxybenzohydrazide
The title compound, C12H10N2O3, exists in the E conformation. The five-membered ring and the phenyl rings form dihedral angles of 36.73 (10) and 12.22 (10)°, respectively, with the central C(=O)N2C unit. The crystal packing is dominated by strong N-H⋯O and O-H⋯N hydrogen bonds. Together with weaker C-H⋯O inter-actions, these establish a three-dimensional supra-molecular network.
