Abstract
The new complex (NH4)[Fe(dipic)2] (1) (dipicH2 = 2,6-pyridinedicarboxylic acid), was synthesized and characterized by elemental analysis, FTIR and UV–Vis spectroscopy and single crystal X-ray method. The crystal system is tetragonal with space group I41/a. The FeIII ion and the N atom of the ammonium cation are located on a crystallographic fourfold rotoinversion axis (4¯). The NH⋯O and CH⋯O intermolecular hydrogen bonding and π⋯π stacking interactions play an important role in the formation of a 3-dimensional anion-cation network and stabilization of the crystal structure. The redox behavior of the complex was also investigated by cyclic voltammetry.
