Figure 6
Detail of the hydrogen bonding operating in the crystal structure of (II). The charge-assisted amino-N—H⋯Cl− hydrogen bonds are shown as orange dashed lines and lead to zigzag chains along [001]. The charge-assisted imino-N+—H⋯O(water) hydrogen bonds are shown as blue dashed lines and both water-O—H⋯Cl− and water-O—H⋯O(water) hydrogen bonds are shown as brown dashed lines. For reasons of clarity, H atoms not involved in hydrogen bonding have been omitted. |
