Figure 6
The two-dimensional supramolecular sheets that lie parallel to the ab plane are linked via O—H⋯N interactions, represented by dashed blue lines, between the water molecules of one sheet and azide anions of another sheet to form a three-dimensional supramolecular framework. The discussed C—H⋯N hydrogen bonds between neighboring dpa ligands and azide anions within the coordination sphere of the CoIII cation are represented by dashed yellow lines, and the C—H⋯O, N—H⋯O, and O—H⋯O hydrogen bonds linking the anions, complex cations, and water molecules into sheets are represented by dashed red lines. For clarity hydrogen atoms not involved in hydrogen-bonding interactions have been omitted. |
