Figure 3
A stereoview of the crystalline architecture of (I), projected approximately down the b axis. Zn, N and O atoms are shown as darkened spheres. Note the tight solvent-free organization of the layered assemblies (three layers are viewed edge-on). The O—H⋯N hydrogen bonds and weak Zn⋯NC coordination in each layer are indicated by thin lines. H atoms have been omitted, except for the hydroxylic H atoms of the three central molecular units which are involved in hydrogen bonding. |
