X-Ray crystal structure of a planar, high-spin iron(II) complex of a pentadentate unsaturated macrocycle formed by reaction of 2,9-di(1-methylhydrazino)1,10-phenanthroline monohydrochloride with 2,6-diacetylpyridine

Abstract

The crystal structure of a high spin iron(II) complex with a pentadentate nitrogen macrocycle, that bears certain structural similarities to porphyrins, demonstrates that the metal ion sits in the ligand plane, a stereochemistry that is attributed to the slightly larger hole size relative to porphyrins.
