Figure 9
Part of the crystal structure of polymorph B, showing the C4 chain formed by the weak C133—H133⋯O132(x, −y + [{3\over 2}], z + [{1\over 2}]) hydrogen bond (dashed lines) which links together mol­ecules of type 1. The chain runs parallel to the a axis. H atoms not involved in hydrogen bonding have been omitted.
