Figure 5
Stereoviews of polymorphs (II) (top) and (III) (bottom). The stacking of the planar molecules is only shown at the periphery of the figure in order to focus on the hydrogen-bonding patterns in the immediate vicinity of the title molecule. The view is selected such that the title molecules are placed in the same orientation. The stacking motif is in the direction of the shortest axial length, namely the a axis in (II) and the b axis in (III). |
