Abstract
Molecular salts formation is a simple and widely used approach to alter the physicochemical properties of active pharmaceutical ingredients, such as ciprofloxacin (CP), without modifying their chemical structures. In the current work, two co-crystals of p-coumaric acid (PCMA) and organic salts of CP cation (CPH) were prepared and characterized in solid state by X-ray diffraction and by NMR spectroscopy in solution. The two organic salts are CPH:benzoate anion (CPH:BA) and CPH:salicylate anion (CPH:SA). To our knowledge, these are the first two examples of co-crystals of CPH organic salt and a different organic acid. In the two co-crystals (CPH:BA:PCMA and CPH:SA:PCMA), the anion (BA or SA) connects the PCMA molecules and the CPH via O–H∙∙∙O and N–H∙∙∙O hydrogen bonding interactions. The ratio between the three crystalline species in the two co-crystals (CPH:BA:PCMA and CPH:SA:PCMA) is (1:1:1), the ratio was confirmed in solution by NMR spectroscopy.
