摘要

Reaction of pyridine-2,6-dicarbaldehyde with hexane-3,4-dione and ammonium acetate affords 2,6-bis(4,5-diethyl-1 H -imidazol-2-yl)pyridine (L) which was used as ligand in the synthesis of iron( ii ) chloride complex [FeL 2 ]Cl 2 •H 2 O. Conclusions about the structure of the coordination site of the complex were drawn based on the results of IR spectroscopy, EXAFS spectroscopy, static magnetic susceptibility studies, and quantum chemical calculations.
