Abstract
The title compound, C23H16N4O4, can be considered as consisting of two conn ected fragments: a nitrophenyl-hydrazone moiety, which assumes an E configu ration, and an isoxazole moiety. In this latter fragment, the weak pi-elect ron delocalization shortens the carbonyl-isoxazole O ... O distance [2.643 (2) Angstrom] to less than the van der Waals radii sum.
