Figure 8
Part of the crystal structure of polymorph B, showing the C₂²(13) chain formed by the weak C16—H16⋯O231(x + 1, y, z) hydrogen bond (dashed lines) linking the molecules in the asymmetric unit. The chain runs parallel to the a axis. H atoms not involved in hydrogen bonding have been omitted.
