Coordination Oligomers and Polymers of an Oxazole-appended Zinc Chlorophyll Derivative

The self-assembled structures of an oxazole-appended zinc chlorophyll derivative in solution and in a crystal are reported. Cyclic oligomers formed in chloroform, while staircase-like coordination polymers formed in the crystal, both mediated by intermolecular axial coordination of the nitrogen atom in the oxazole moiety to the zinc center in another chlorophyll molecule.
