Figure 3
Part of the crystal structure of polymorph (I

), showing a hydrogen-bonded chain running along the [0 $[\overline 1]$ 3] direction. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Cg3 is the centroid of ring C31–C36. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( $[{5 \over 4}]$ − x, y − $[{1 \over 4}]$ , $[{3 \over 4}]$ + z) and ( $[{5 \over 4}]$ − x, $[{1 \over 4}]$ + y, z − $[{3 \over 4}]$ ), respectively.
