Figure 2
Molecular packing for four benzocaine polymorphs shown along with selected crystallographic directions. The ribbons are distinguished by different colours. Packing for polymorphs (I)–(III) are shown for previously reported structures (Chan et al., 2009): QQQAXG04 [polymorph (I)], QQQAXG05 [polymorph (II)] and QQQAXG03 [polymorph (III)]. |
