• Single-crystal X-ray diffraction was employed to determine the crystal structure.
• Analysis of bond lengths, bond angles, dihedral angles, and hydrogen bonding networks.

Main Results:

• The molecule adopts a trans configuration around the C=N bond.
• A small dihedral angle (8.98°) was observed between the benzene ring and the hydrazinecarboxylate plane.
• Intramolecular hydrogen bonds (O-H⋯N and C-H⋯N) and intermolecular N-H⋯O hydrogen bonds forming chains along the c-axis were identified.
• C-H⋯π interactions were also observed in the crystal structure.

Conclusions:

• The crystal structure of C(10)H(12)N(2)O(3) has been successfully determined.
• The compound exhibits specific conformational preferences and a rich network of hydrogen bonding and other non-covalent interactions.
• These findings contribute to the understanding of structure-property relationships in organic molecules.
