Figure 4
A part of sheet structure, showing the R44 graph-set motif generated by classical O—H⋯O and N—H⋯O hydrogen bonds. Yellow lines indicate the intermolecular O—H⋯O and N—H⋯O hydrogen bonds. Only H atoms involved in the hydrogen bonds are shown for clarity. [Symmetry codes: (i) −x + 1, y – 1/2, −z; (ii) x – 1, y, z; (iv) −x, y − , −z.] |
