Figure 2
A stereoview of the specific intermolecular interaction scheme in (I). Zn, N and O atoms are shown as darkened spheres. The methanol-to-pyridyl O—H⋯N hydrogen bonds [O⋯N = 2.751 (6) Å] and the Zn⋯NC contacts [Zn⋯N = 3.020 (5) Å] are indicated by thin lines. Note the two-dimensional assembly that forms with a corrugated surface. H atoms have been omitted for clarity, except for the hydroxylic H atoms in four of the porphyrin units (in the lower left corner) which are involved in hydrogen bonding. |
