Figure 4
(a) A partial view of the crystal packing of L2-I

, showing the formation of the N—H⋯N and N—H⋯O hydrogen-bonded dimers (dashed lines; see Table 2

for details). H atoms not involved in hydrogen bonding have been omitted for clarity. (b) A view, along the b axis, of the crystal packing of polymorph L2-I

, showing the N—H⋯O and N—H⋯N hydrogen bonds as light lines (cyan in the electronic version of the paper). H atoms not involved in hydrogen bonding have been omitted for clarity. See Table 2

for details.
