In the asymmetric unit of the title compound, C16H14N4O2·0.5C4H8O2, there are two crystallographically independent oxime mol-ecules and one solvent mol-ecule. Each oxime mol-ecule has intra-molecular N - H⋯O and N - H⋯N hydrogen bonds, which make the non-H atoms approximately coplanar except for the naphthyl groups. The two independent mol-ecules are connected to each other by O - H⋯N hydrogen bonds, forming a dimer. Dimers are linked into a layer through C - H⋯O, C - H⋯N and C - H⋯π inter-actions. There is π-stacking of approximately parallel oxadiazole rings, with a centroid-centroid distance of 3.6234 (9) Å and a dihedral angle of 8.90 (6)°. Dioxane C and H atoms are disordered over two sites each, with occupancy factors of ca 0.78:0.22.
