Abstract
Two isostructural compounds (C17H22FN3O3)[MCl4]·H2O (M = Cd, Hg), C17H20FN3O3 is 1-ethyl-N-methyl-6-fluoride-1,4-dihydro-4-oxo-7-(4-methyl-1-piperazinyl)-3-quinoline carboxylic acid (PefH, pefloxacin), are synthesized and their crystal structure is determined. The crystals contain PefH32+ and MCL42- ions. The neighboring [MCl4]2- ions are bonded together by two bridging water molecules through four Cl⋯(H-O-H)2⋯Cl hydrogen bonds with the formation of the supramolecular motif R24(8) The supramolecular architecture of crystals is analyzed.
