4-Nitro-N'-[(E)-3-pyridylmethyl-idene]benzohydrazide

Abstract

In the title moleclue, C(13)H(10)N(4)O(3), the methyl-idene-hydrazide [-C(=O)-N-N=C-] fragment is essentially planar, with a maximum deviation of 0.0228 (7) Å. The mean planes of the benzene and pyridine rings make dihedral angles of 25.44 (6) and 5.47 (7)°, respectively, with the mean plane of the methyl-idene-hydrazide fragment. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link mol-ecules into chains along the b axis. Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds. The O atoms of the nitro group are disordered over two sets of sites of equal occupancy.
