Figure 2 Molecular packing for (I) viewed along the a axis. Dashed lines indicate N—H⋯O intermolecular hydrogen bonds supported by a weak C—H⋯O intermolecular interactions link the molecules into dimers forming R22(10) graph set motifs. Also, weak C—H⋯O intermolecular interactions are observed which interlink the dimers and influence the crystal packing. H atoms not involved in hydrogen bonding have been removed for clarity. |
