Abstract
The title compound, C23H17FN2O3, crystallizes with two independent molecules in the asymmetric unit. The molecules are connected by pairs of N—H⋯O hydrogen bonds and have slightly different conformations, as indicated by the dihedral angles between the central imidazolidine-2,4-dione ring and its three substituents. In one molecule, these are 60.56 (1) and 82.66 (9)° to the phenyl rings and 84.35 (16)° to the 2-(4-fluorophenyl)-2-oxoethyl side chain. In the other molecule, the corresponding angles are 66.35 (10), 84.94 (9) and 86.31 (16)°. In the crystal, weak C—H⋯O interactions leading to a three-dimensional supramolecular architecture.
