Figure 3
The crystal packing of (Ib) at 110 K, viewed along the crystallographic b axis. The twofold screw axes are shown with black symbols and inversion centers are shown with unshaded circles. The unit cell of the high-temperature α phase is drawn with dashed lines; symbols for the screw axes and the inversion centers are shown shaded. Mol­ecules of (Ia) are not displayed. [In the electronic version of the paper, for the mol­ecules of (Ib), orange represents mol­ecule 1 (X = 1), yellow mol­ecule 2 (X = 2), blue mol­ecule 3 (X = 3), green mol­ecule 4 (X = 4), red mol­ecule 5 (X = 5) and black mol­ecule 6 (X = 6).]
