Figure 3
Part of the crystal structure of (I[link]), showing the formation of an R22(8) dimer centred at ([1 \over 2], [1 \over 2], [1 \over 2]). For clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*) are at the symmetry position (1 - x, 1 - y, 1 - z).  [article HTML]
