Figure 5
Projection diagrams for (V) viewed (a) normal to the (040) plane and (b) normal to the (220) plane, with packing motifs highlighted. In (c), the (040), (220) and (20) planes are viewed edge-on and their locations shown by highlighted lines through them. The channels in (V) are completely specified by these three families of planes. The C and N atoms for the two unique urea molecules in (V) are indicated by filled and open spheres of arbitrary radii. All H atoms are shown as small open spheres for clarity. |
