The synthesis, characterization, and theoretical studies of a novel hydrazine, N,N’-bis-(3-quinolylmethylene)diphenylethanedione dihydrazone (1) has been reported. The molecular structure has been characterized by room-temperature single-crystal X-ray diffraction which reveals that two quinoline moieties are disposed nearly perpendicularly around the central C-C bond giving a ‘L’ shape of the molecule. This particular geometry gives rise to the hydrogen-bonded supramolecular rectangle of two self-complementary molecules. These supramolecular units are further assembled by π-π interaction. The Hirshfeld surface analysis of compound 1 shows that C···C, C···H, H···H, and N···H interactions of 13.1, 9.9, 52.3, and 7.4%, respectively, which exposed that the main intermolecular interactions were H···H intermolecular interactions.
