Abstract
The crystal structure of N-(4-hexyloxybenzylidene)-p-toluidine (1) was determined at 150, 273, 295, and 320 K. Compound 1 was studied by differential scanning calorimetry (DSC). According to the DSC analysis, compound 1 exhibits monotropic mesomorphism associated with Cr-Iso-N-S-Cr phase transitions. The crystal packing is built up from alternating loosely packed aliphatic and closely packed aromatic regions, which is typical of enantiotropic mesomorphic compounds. In the closely packed regions, there are two types of weak directional interactions, such as π⋯π stacking interactions and weak C-H O hydrogen bonds, which link the molecules into centrosymmetric dimers. The thermal behavior of compound 1 and its relation to the crystal packing are discussed.
