Creation of a Nonsymmetric Dimethanolpyridine Ligand: A Rare Zn(salphen) Template Effect

An interesting reversible, templated synthesis of unsymmetrical
pyridine-ligated Zn complexes has been observed in solution and
solid-state phases when Zn(salphen) complexes are reacted with
methanol-substituted pyridine substrates. The X-ray molecular
structure of an unusual Zn3 supramolecular assembly is reported,
in which the central Zn atom is embedded in a distorted octahedral
geometry and each of the single anionic O atoms of the pyridine
groups coordinates to a Zn(salphen) unit.
