Article abstract of DOI:10.1007/BF01161037

Several alkyl-, aralkyl-, and aryl-substituted diammonium μ-oxobis salts, of potential interest as model compounds for the study of certain electrophysical and biological processes, are synthesized via the corresponding tetrachloroferrate(III) salts and are characterized by IR and Raman spectroscopy.A structure analysis is performed on the representative bis(benzyldimethylphenylammonium) μ-oxobis(trichloroferrate).The (tetracoordinate) iron atoms in the oxo-bridged dinuclear anoin of the salt each possess an ever so slightly distorted tetrahedral ligand environment; the bridge geometry compares well with that of other salts containing the ^2- anion.Crystallographic Data: a = 26.392(5) Angstroem, b = 14.015(3) Angstroem, c = 9.638(2) Angstroem, β = 92.65(2) deg, and Z = 4; space group P2₁/n.R(F) = 0.070, R_w(F) = 0.078 for 4447 observed reflections.
