Abstract

In the title compound, C(15)H(9)F(4)N(3)O(2)S, the N,N'-disubstituted thio-urea fragment adopts a cis,trans geometry, stabilized by an intra-molecular N-H⋯O hydrogen bond to the carbonyl O atom of the tetra-fluoro-benzoyl group. The central thio-urea group makes dihedral angles of 47.79 (7) and 35.54 (8)° with the two aromatic rings. In the crystal, mol-ecules are linked via N-H⋯O and N-H⋯S hydrogen bonds into two-dimensional polymeric structures parallel to (100). In turn, π-π stacking inter-actions between tetra-fluoro-benzene and benzene units [centroid-centroid distance = 3.996 (10) Å; dihedral angle = 13.60 (8)°] organize these two-dimensional assemblies into a three-dimensional framework.
