%X Orthorhombic crystals of rafoxanide, C19H11Cl2I2NO3, belong to the space group Pca21 with a 23.234(2), b 8.980(2), c 9.582(2)&#506; and Z 4. The structure was solved by the heavy-atom method from diffractometer data measured with Mo K&#945; radiation. Refinement with anisotropic temperature factors given to the non-hydrogen atoms converged at R 0.059 for the 2025 observed terms. The two aromatic rings of the salicylanilide moiety are almost coplanar with a dihedral angle of 11.2&#176;, whereas they are approximately perpendicular to the plane of the phenoxy group. Weak inter-molecular hydrogen-bond-like interactions between the nitrogen and carbonyl oxygen, which involve a glide motif, link the molecules into ribbons extending along the c axis.
