The title compound, C(16)H(14)FNOS, crystallizes with Z' = 2 in the space group P2(1)/c. In one of the two independent molecules, the heterocyclic ring is effectively planar, but in the other molecule this ring adopts an envelope conformation. The molecules are weakly linked by two C-H···O hydrogen bonds to form C(2)(2)(14) chains. Comparisons are made with some symmetrically substituted 2-aryl-3-benzyl-1,3-thiazolidin-4-ones.
