چکیده
In the title compound, C18H12O2, the benzene rings are inclined to one another by 66.79 (7)°. The five-membered ring is almost planar with a maximum deviation of 0.014 (1) Å. In the crystal, the mol-ecules are linked by pairs of weak C-H⋯O interactions into centrosymmetric dimers. These dimers are linked by C-H⋯π interactions, forming a three-dimensional structure.

In the title solvate, C19H13N5O·0.5C4H8O2, the main mol-ecule is almost planar (r.m.s. deviation for the non-H atoms = 0.066 Å). The hydroxyl-amine group is disordered over two orientations in a 0.761 (4):0.239 (4) ratio. The complete dioxane solvent mol-ecule is generated by a crystallographic inversion centre. In the crystal, both disorder components of the hydroxyl-amine group form O-H⋯N hyd...
