Figure 3
The self-rotation function is shown for the indicated sections. Polar angles of the main noncrystallographic symmetry axes are reported. The twofold axes in the κ = 180° section may be generated by internal twofold symmetry of the RZZ complex (which is likely to form a 2:2:2 hexamer) as well as the likely presence of two RZZ complexes in the asymmetric unit of the crystal. The single asterisk in the central panel marks the crystallographic threefold axis. The double asterisk in the right panel marks the `bleed-through' of the threefold axis in the 90° section. Peaks B and D and peaks C and E are symmetry-related. The relative heights of the peaks (origin peak = 100) were as follows: peak A, 98.8; peak B, 56.4; peak C, 50.2; `bleed-through' peak of the crystallographic threefold axis, 49.
