Abstract
Several alkyl-, aralkyl-, and aryl-substituted diammoniumμ-oxobis[trichloroferrate(III)] 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 anion of the salt each possess an ever so slightly distorted tetrahedral ligand environment; the bridge geometry [Fe-O distances 1.757(5) and 1.775(5) Å, Fe-O-Fe angle 147.7(3)°] compares well with that of other salts containing the [Cl3Fe-O-FeCl3]2- anion. Crystallographic Data:a=26.392(5) Å,b=14.015(3) Å,c=9.638(2) Å,β=92.65(2)°, andZ=4; space groupP21/n.R(F)=0.070,R W (F)=0.078 for 4447 observed reflections.
