Figure 6.
Fig. 6. Close-packed layers of the mumps P NBD formed within
the crystal. (a) Schematic ribbon diagram showing the packing
arrangement of molecules in the xy-plane of the crystal. The two
molecules within the asymmetric unit are shown in light blue.
Symmetry-equivalent molecules are shown in gray. For clarity,
only a single molecular layer is shown. As depicted, the
noncrystallographic twofold rotation axis lies parallel with the
crystallographic z-axis. (b) A molecular (Connolly) surface
representation of the region shown in (a) calculated using the
program PyMOL.
