Figure 3
Part of the crystal structure of (I), showing the R66(18) and R66(30) rings formed by O—H⋯O and C—H⋯O hydrogen bonds (shown as dashed lines); symmetry codes are as given in Table 1. 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. |
