Figure 2 Diagram showing the intermolecular N—H⋯O and O—H⋯N hydrogen bonding network in the structure of (I). Molecules related by translation along the b axis are held together by the N1—H1A⋯O1 hydrogen bond. In addition, molecules related by the 2 fold screw axis along c are held together by the O1—H1⋯N1 and N1—H1B⋯O1 hydrogen bonds which appear as a stack of molecules when viewed down the c axis. |
