Abstract
Abstract The structure and thermal properties of mesomorphic phenyl benzoate CH 3 –C(O)–C 6 H 4 –OC(O)–C 6 H 4 –OC 9 H 19 ( I ) were studied by differential scanning calorimetry (DSC) and X-ray diffraction. The crystal packing of I is typical of mesomorphic crystals. It consists of alternating loosely packed aliphatic and closely packed aromatic regions, the latter regions being stabilized by weak directional C–H···π interactions. According to the DSC data, compound I does not form a mesophase upon melting. The latter was observed only upon cooling of the isotropic melt. The lack of enantiotropic mesomorphism in the crystal of I is attributed to the fact that C–H···π non-covalent interactions, which could ensure the structuring of the melt, are broken at the melting point.
