Abstract
The title compound, C25H26Cl2FN3O4S, contains two bioactive moieties (thiobarbituric acid and fluoroquinolone). In the crystal, molecules are linked via C-H center dot center dot center dot O and C-H center dot center dot center dot F hydrogen bonds, forming two-dimensional slab-like networks lying parallel to the bc plane. The benzene ring substituted by F and Cl atoms and the 4-chlorobutyl group seem to be partly disordered, however attempts to model the disorder were unsuccessful.
