Synthesis, characterization, crystal structure and Hirshfeld surface analysis of o-tolyloxy acetic acid (1H-indol-3-yl-methylene)-hydrazide

o-Tolyloxy acetic acid (1H-indol-3-yl-methylene)-hydrazide was synthesized by treating 2-methyl phenoxy acetic acid hydrazide with indole carboxaldehyde. It was characterized by NMR, IR studies and mass spectral studies and finally, the structure was confirmed by single crystal X-ray diffraction studies. The title compound C18H17N3O2 crystallizes in the monoclinic crystal system in the space group P21/n. The intermolecular interactions in the crystal structures are quantified using the Hirshfeld surface analysis method. The majority contribution to the Hirshfeld surfaces is from H⋯H (45.4%) contacts.
