Crystal structure of (RS)-4-(3-carboxy-1-ethyl-6,8-difluoro-4-oxo-1,4-dihydroquinolin-7-yl)-2-methylpiperazin-1-ium 3-carboxy-5-fluorobenzoate

Crystal structure of (RS)-4-(3-carboxy-1-ethyl-6,8-difluoro-4-oxo-1,4-dihydroquinolin-7-yl)-2-methylpiperazin-1-ium 3-carboxy-5-fluorobenzoate

In the title organic salt, C17H20F2N3O3+·C8H4FO4−, proton transfer leads to one protonated lomefloxacin molecule (HLf+) and one 3-carboxy-5-fluorobenzoate (5-F-Hip−) anion in the asymmetric unit. The HLf+ cation is bent, with a dihedral angle of 38.3 (1)° between the quinoline ring and the piperazin...
