Mössbauer Studies of Iron Organometallic Complexes. VII. The Iron (−II) Tetrahedral Compounds

Abstract

Magnetic perturbation was used to determine the electric-field gradient parameters Vzz and η for several tetrahedral Fe(− II) compounds. Because of the spherical symmetry of the 3d10 configuration, only ligand dispositions and strength are measured. Distortions from tetrahedral symmetry are sensitively measured by the magnitude of η.
