(E)-N′-Benzylidene-5-methylisoxazole-4-carbohydrazide

Abstract

The molecule of the title compound, C12H11N3O2, is approximately planar with an r.m.s. deviation of 0.0814 Å from the plane through all the non-H atoms. The dihedral angle formed by the benzene and isoxazole rings is 6.88 (16)°. The molecular conformation is stabilized by an intramolecular C—H...N hydrogen bond, forming an S(6) ring, and the molecule displays an E configuration with respect to the C=N double bond. In the crystal structure, intermolecular N—H...O hydrogen bonds form centrosymmetric dimers which are further linked by weak C—H...N interactions augmented by very weak C—H...π contacts, forming layers parallel to (120).
