Figure 2
Molecular packing: (a) view of the supramolecular layer sustained by hydroxy-O—H⋯O(hydroxy) and hydroxy-O—H⋯O(water) hydrogen bonds, shown as orange dashed lines. Only the pyridyl N atoms of the 3-pyridinealdazine ligands are shown. (b) A side-on view of the layer in (a) extended to show the two central 3-pyridinealdazine ligands (see text). The putative water-O—H⋯N(pyridyl) hydrogen bonds are shown as blue dashed lines. In both images, only acidic hydrogen atoms are included. |
