Abstract
Reported herein are the magnetic and structural properties as well as solution equilibrium investigation for a pair of iron (II) pyridyl-imidazoline complexes: [Fe(pizMe)Cl2]2 (1) and [Fe(pizMe)3](FeCl4) (2), where pizMe=2-(2′-pyridinyl)-4,5-dihydro-1-methylimidazole. Dinuclear complex 1 contains high-spin iron (II) centers and a “flat” pizMe ligand (planar at the imidazoline N atom), while the pizMe-containing complex in 2 exhibits characteristics of a low-spin iron (II) center and a pyramidalized pizMe ligand. In solution, the two complexes are present in equilibrium as evinced through NMR and electronic absorption spectral studies. Spin-state switching between 1 and 2 in methanolic solution is a result of ligand lability.
