An intramolecular N\u2014H...N hydrogen bond stabilizes the molecular conformation. Intermolecular N\u2014H...N hydrogen bonds, as well as C\u2014H...N hydrogen bonds, lead to the formation of supramolecular chains extending parallel to [001]. The intermolecular interactions were quantified and analysed using Hirshfeld surface analysis, revealing that H...H interactions contribute most to the crystal packing (37.4%).
