Abstract
The crystal structure of benzoic acid 4-nitrobenzylidenhydrazide has been determined. Crystal data: crystal system — monoclinic, a = 7.101(9) Å, b = 25.48(3) Å, c = 7.730(11) Å; β = 112.43(9)°, space group P21/n, Z = 4, R = 0.038. The compound under investigation has a non-planar structure in general, and the substituents at azomethine N-C bond are in E-position. Root-mean-square planes of the six-memebered heterocycles make angles of 29.9° and 37.7° to fairly planar hydrazine fragment. In crystalline state the compound forms layers, the molecules within the layers being linked by C-H...O bonds. Neighboring layers are connected by hydrogen bonds between carbonyl oxygen atoms and amide hydrogens.
