Abstract
The title compound, C16H14BrN3O5, is a novel halogen (Br) substituted hydrazine derivative. The hydrazine derivatives were the group of compounds with the general structure, R1R2C=NNH2 (Uppal et al., 2011), with the central RC=NNH2 moiety bridging two different groups on both sides. An all-trans configuration of the backbone (RC=NNH2) results in an extended molecular conformation. The dihedral angle between the 5-bromo-2-methoxyphenyl ring and the nitrophenyl ring is 4.4 (3)degrees. Intramolecular N-H center dot center dot center dot O interactions form S(6) graph-set motifs, while C-H center dot center dot center dot O and C-H center dot center dot center dot N interactions form S(5) graph-set motifs. Symmetry-related molecules are linked by C-H center dot center dot center dot O inter-molecular interactions forming an R-2(1)(10) graph-set motif. There are nearly face-to-face directional specific pi-pi stacking interactions between the centroids of the nitrophenyl ring and the benzene ring of the 5-bromo-2-methoxy group [centroid-centroid distance = 3.6121 (5) angstrom and slippage = 1.115 angstrom], which also contributes to the molecular packing. The Hirshfeld surface analysis was performed in order to visualize, explore and quantify the intermolecular interactions in the crystal lattice of the title compound.
