Figure 4
Part of the crystal structure of (I), showing the R44(26) rings formed by O—H⋯O and C—H⋯O hydrogen bonds (grey dashed lines), as well as the intermolecular O—H⋯π interactions (black dashed lines). Symmetry codes are as given in Table 1; the centroid (Cg1) of the C1A–C5A/C10A benzene ring is denoted by a small sphere. In order to differentiate molecules A and B, all H atoms of molecules A are included, while the H atoms of molecules B, except for atoms H11B and H12B, have been omitted. |
