Abstract

Planar chloro aromatics usually adopt a sheet/ribbon based 4 Åshort axis structure, but when the molecule has a significant permanent dipole moment, an inverted layer motif characterized by axis doubling is obtained. This is exemplified by the title compounds. The packing of several related derivatives is analysed.
