The iron-57 Mössbauer spectra of the eight-coordinate complex, [Fe(L(N4))2](BF4)2, where L(N4) is the tetradentate N(1)(E),N(2)(E)-bis[(1-methyl-1H-imidazol-2-yl)methylene]-1,2-benzenediimine ligand, have been measured between 4.2 and 295 K and fit with a quadrupole doublet. The fit at 4.2 K yields an isomer shift,...
