Figure 4
A view along the c-axis of the crystal packing of polymorph I, showing the hydrogen bonds as dashed lines (Table 2

). The minor component atoms of the positionally disordered phenyl ring (atoms C6B–C11B) are shown in pale green. For clarity, only the H atoms (small white spheres) involved in hydrogen bonding have been included.
