Abstract

The crystal structures of two concomitant conformational polymorphs of 1,3,5-tris(4-chlorobenzoyl)benzene are described. Both polymorphs self-assemble into discrete network architectures mediated by weak C–H⋯O and C–H⋯Cl hydrogen bonding in one case and multiple C[double bond, length as m-dash]O⋯Cl and Cl⋯Cl interactions in the other. The thermochemical properties of these polymorphs were examined using differential scanning calorimetry.
