Figure 3
Part of the crystal structure of the orthorhombic polymorph, (Ib

), showing the linking of C(8) spiral chains parallel to [010] into a (100) sheet of R²₄(12) and R⁴₄(28) rings. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*) or hash (#) are at the symmetry positions (1 − x, −½ + y, ½ − z) and (x, $[3 \over 2]$ − y, ½ + z), respectively.
