TL;DR: The benzene rings of C11H14N2O3 are stacked with their centroids separated by 3.777 (1) A, indicating π−π inter-actions as mentioned in this paper.
Abstract: The molecule of the title compound, C11H14N2O3, adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the hydrazinecarboxylate plane is 12.06 (9)°. Molecules are linked into a one-dimensional network by N—H⋯O hydrogen bonds and C—H⋯π interactions. The benzene rings of inversion-related molecules are stacked with their centroids separated by 3.777 (1) A, indicating π–π interactions.

TL;DR: In the title compound, C9H10N2O3, the hydroxy group and the C=N—N unit are coplanar with the benzene ring, indicating weak π–π interactions.
Abstract: In the title compound, C9H10N2O3, the hydroxy group and the C=N—N unit are coplanar with the benzene ring. The benzene rings of inversion-related molecules are stacked with their centroids separated by a distance of 3.7703 (9) A, indicating weak π–π interactions. In the crystal structure, C—H⋯O, O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds link molecules into a infinite two-dimensional network along the a axis.

TL;DR: In this article, the title compound, C10H12N2O4, adopts a trans configuration with respect to the C=N double bond and the non-H atoms are essentially coplanar, with a maximum deviation of 0.015
Abstract: The title compound, C10H12N2O4, adopts a trans configuration with respect to the C=N double bond. The non-H atoms of the molecule are essentially coplanar, with a maximum deviation of 0.015 (2) A. An intramolecular O—H⋯N interaction is observed. In the crystal structure, the molecules are linked into a two-dimensional network parallel to the ac plane by N—H⋯O hydrogen bonds involving the methoxy O atom and by two C—H⋯O hydrogen bonds involving the carbonyl O atom. In addition, an intermolecular C—H⋯π interaction is observed.
