Figure 1
The independent molecular components of (I)

, with the atom-labelling schemes, showing (a) molecule 1, (b) a single orientation of molecule 2, and (c) the four orientations of molecule 2 across a site of 2/m symmetry at (0, 0, $[1\over2]$ ), where the symmetry positions denoted by the suffixes B, C and E are (−x, y, −z + 1), (−x, −y, −z + 1) and (x, −y, z), respectively. In (c), the orientation of the molecule at (x, y, z) and the viewpoint are the same as in (b). Displacement ellipsoids are drawn at the 30% probability level.
