Figure 3
Unit-cell overlay and depiction of the π–π interactions along [100] in the crystal structure of 2-methyl-1,4-phenylene bis(3,5-dibromobenzoate), giving parallel but slipped central 1,4-benzene rings (shaded green) and end group 3,5-dibromophenyl rings (shaded blue). The centroids of the central benzene rings lie on inversion centers, giving equal Cg⋯Cg distances that correspond to the a lattice parameter [3.8875 (1) Å] with ring centroids shifted by 1.905 Å (central benzene rings) and 1.726 Å (3,5-dibromophenyl rings). Displacement ellipsoids are shown at the 50% probability level. |
