Abstract

In the title compound, C5H5N3O, the isoxazole ring is essentially planar, with a maximum deviation of 0.007 (1) Å from the least-squares plane. The N atom of the amine group exhibits sp 2 character (sum of bond angles around this atom = 358°). In the crystal, mol­ecules are aggregated by two kinds of N—H⋯N hydrogen bonds into fused R 2 2(12) and R 6 6(26) rings, forming a slightly puckered two-dimensional array lying parallel to (101).
