In the present study, ciprofloxacin-salicylic acid molecular salt has been synthesized and preliminarily characterized by FT-IR spectroscopy. The single crystal X-ray diffraction (SCXRD) reveals the proton transfer from carboxylic acid group of salicylic acid to piperazine moiety in ciprofloxacin confirming the formation of new molecular salt. The molecular packing of the molecular salt is mainly supported by N+–HO, O–HO, C–HF, C–H, and interactions. The 3D Hirshfeld surfaces and the associated 2D fingerprint plots were investigated for intermolecular hydrogen bonding interactions.
