Figure 7
Part of the crystal structure of VOGSEP (Belskii et al., 1990), showing a sheet parallel to the (001) plane formed by O—H⋯O (thin dashed lines), O—H⋯π (thick grey solid lines) and C—H⋯π (thick dashed lines) hydrogen bonds. All aromatic H atoms not involved in these interactions have been omitted for clarity. The centroids of aromatic rings are denoted by small black spheres. |
