Figure 1 Schematic representation of the two crystallographically independent [Si2O(OH)(Ph)5] molecular units comprising the asymmetric unit of (I) showing the labelling scheme for all non-H atoms. Displacement ellipsoids are drawn at the 50% probability level and H atoms associated with the hydroxyl groups are represented as small spheres with arbitrary radii. All H-atoms bound to carbon were omitted for clarity. The O—H⋯O hydrogen bond and O—H⋯π contact connecting neighbouring binuclear units are represented as green and orange dashed lines, respectively. |
