3-[2-(4-Fluorophenyl)-2-oxoethyl]-5,5-diphenylimidazolidine-2,4-dione

Abstract

The title compound, C23H17FN2O3, crystallizes with two independent molecules in the asymmetric unit. The molecules are connected by pairs of N - HO 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 - HO interactions leading to a three-dimensional supramolecular architecture. © Mague et al. 2014.
