Figure 2
Crystal packing diagram of the title compound (CERIUS2; Accelrys Molecular Simulations), showing the network of hydrogen bonds (dashed lines) that give rise to a ribbon structure. Molecules with the same torsion-angle values are drawn in the same way (cylinders or balls and sticks). Only four molecules of the unit cell are drawn in order to simplify the representation. The unit cell is composed of four additional molecules that constitute a new ribbon shifted by a/2 and b/2 along the a and b axes, respectively. |
