Abstract |
Two zinc porphyrin complexes were synthesized by one-port reaction. Compound 1 is a mononuclear complex. The zinc ion is bound in the cavity of the ligand and it is coordinated by five atoms in a square pyramidal geometry. Whereas in 2, the metal ion is coordinated by six nitrogen atoms in an octahedral conformation. The porphyrin ligand is coordinated to three zinc ions with a eta 1-eta 1-eta 4-mu 3 coordination mode. Six neighboring zinc atoms constitute a six-numbered ring in a chair structure. Besides, three neighboring zinc atoms form another triangle helical structure and the structure extends into a three-dimensional metallic polymer. |
