%X The crystal structure of the title compound, C20H4Cl6O5,C6H6, has been determined by single-crystal X-ray diffraction at 298 K. Crystals are monoclinic, C2/c, a 7.258(4), b 19.530(7), c 17.027(11) &#506;, &#946; 93.59(3)&#176;, Z 4. Both pigment and solvent molecules are located about crystallographic 2 axes; the pigment molecule is considerably distorted as a result of interaction between substituent chlorine atoms on adjacent rings.
