چکیده
The mol-ecule of the title compound, C(10)H(12)N(2)O(3), adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the hydrazinecarboxyl-ate plane is 14.6 (1)°. Mol-ecules are linked into a three-dimensional network by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and by C-H⋯π inter-actions.
