Figure 8
The extended one-dimensional chain arrangement of (IV) [containing the R22(8) ring motif] along the a axis, formed through the (N—H⋯)(N—H⋯)O=P hydrogen bonds. The hydrogen bonds are shown as black dashed lines. H atoms not involved in hydrogen bonding have been omitted for clarity and the P(O)(NH)2 segments involved in hydrogen bonding are shown as `capped sticks'. |
