The compound C(9)H(10)N(2)O(2) has 13 non-hydrogen atoms that are nearly planar, with slight deviations influenced by oxygen atoms.
An intra-molecular hydrogen bond between the hydroxyl and nitrogen stabilizes its conformation, which features an E configuration around the N=C double bond.
Additionally, inter-molecular hydrogen bonds form between the hydroxyl and carbonyl oxygen atoms, creating a flat double-layer structure that stacks along the a-axis, facilitated by C-H⋯π interactions.
