ABSTRACT
In the title compound, C25H12Cl6O4, the two carbonyl groups are oriented in a same direction with respect to the naphthalene ring system and are situated roughly parallel to each other, while the two 2,4,6-tri-chloro-benzene rings are orientated in opposite directions with respect to the naphthalene ring system the carbonyl C-(C=O)-C planes subtend dihedral angles of 45.54â
(15) and 30.02â
(15)° to the naphthalene ring system are. The dihedral angles formed by the carbonyl groups and the benzene rings show larger differences, the C=O vectors being inclined to the benzene rings by 46.39â
(16) and 79.78â
(16)°. An intra-molecular O-Hâ¯O=C hydrogen bond forms an S(6) ring motif. In the crystal, no effective inter-molecular hydrogen bonds are found; instead, Oâ¯Cl and Câ¯Cl close contacts are observed along the 21 helical-axis direction. The Hirshfeld surface analysis reveals several weak interactions, the major contributor being Clâ¯H/Hâ¯Cl contacts.
