Abstract

In the title solvate, C19H13N5O·0.5C4H8O2, the main molecule is almost planar (r.m.s. deviation for the non-H atoms = 0.066 Å). The hydroxylamine group is disordered over two orientations in a 0.761 (4):0.239 (4) ratio. The complete dioxane solvent molecule is generated by a crystallographic inversion centre. In the crystal, both disorder components of the hydroxylamine group form O - H⋯N hydrogen bonds to the same N-atom acceptor, thereby generating [010] chains. The chains encompass [010] channels occupied by the solvent molecules. Aromatic π-π stacking is also observed [shortest centroid-centroid separation = 3.3394 (19) Å].
