A view of the three-dimensional supramolecular architecture of (II), formed by N—H⋯O, O—H⋯O, O—H⋯N and C—H⋯O hydrogen-bond interactions. Dotted lines indicate hydrogen bonds. Yellow indicates the phenyl groups and H atoms not involved in hydrogen bonding have been omitted for clarity. The symmetry codes are as given in Table 3. |
