摘要
The title compound, C17H17FN4O4, is a derivative of ciprofloxacin [1-cyclopropyl-6-fluoro-4-oxo-7-(1-piperazinyl)-1,4-dihydroquinoline-3- carboxylic acid]. The crystal packing is stabilized by intermolecular C-H center dot center dot center dot O hydrogen bonds together with pi-pi electron ring interactions [centroid centroid separations between quinoline rings of 3.5864 (11) and 3.9339 (13) angstrom]. A strong intramolecular O-H center dot center dot center dot O hydrogen bonds is present as well as an intramolecular C-H center dot center dot center dot F interaction.
