    “…The structure of the title thio­urea derivative, C(14)H(16)N(4)O(5)S, features an almost planar central C(2)N(2)OS fragment (r.m.s. deviation = 0.005 Å), an arrangement stabilized by an intra­molecular N—H⋯O hydrogen bond. The terminal rings are twisted out of this plane, the dihedral angle formed with the benzene ring being 33.22 (10)°. …”
