 Title    Darstellung und spektroskopische Charakterisierung von Natriumpentacyano(phosphan/phosphit)ferraten(III) Preparation and Spectroscopic Characterization of Sodium Pentacyano(phosphane/phosphite)ferrates(III) Hidenari Inoue3, Satomi Osone3  
 Abstract    Sodium pentacyanoferrates(III) of the type Na2[Fe(CN)5L] (L = phosphane or phosphite) have been prepared from sodium pentacyanoferrates(II), Na3[Fe(CN)5L], by bromine oxidation and characterized by Mössbauer, IR, and electronic spectroscopy. Isomer shifts and quadrupole splittings lie within the range commonly found in low-spin iron(III) complexes. A linear correlation was found between isomer shifts and CN stretching and Fe-CN bending frequencies, respectively. The spectroscopic parameters show that the d^-d^ back bonding o f the Fe-P bonds is synergetically strengthened with increasing a donor capability of the phosphorus ligands.

 Abstract    In the spinel system F eV 20 4—M gV20 4 pure Fe(II)-spinels could not be prepared. M össbauer spectra show that the solid solution has the com position Fe2+Mg, _t[Fe3+V 2_v] 0 4, with y depend­ ing on the partial pressure o f oxygen during preparation.

 Title    Verteilung und Valenz der Kationen in Spinellsystemen mit Eisen und Vanadium, VIII Gitterkonstanten, Mößbauer-Spektren und elektronische Eigenschaften der Mischkristallreihe FeV20 4—Fe30 4 Distribution and Valence of the Cations in Spinel Systems with Iron and V anadium , VIII Lattice Constants, M össbauer Spectra and Electronic Properties of the Solid Solution FeV20 4—Fe30 4  
 Abstract    From lattice constants and M össbauer data the valence distribution and an energy-level diagram o f the spinel system F e(F evV 2_t) 0 4 have been derived. In the range 0.3 < x ^ 1.5 the transition from normal to inverse spinels takes place. The M ößbauer spectra with 1.0 < jc ^ 2.0 consist o f two sets o f sextets corresponding to tetrahedral and octahedral sites. Typical values o f isom er shift and internal m agnetic field strength due to the different environments o f the iron ion result from the superim posed sextets o f the octahedral site pattern. Neighbouring V ions enhance the conduc­ tion electron density and diminish the strength o f the magnetic interaction. M ößbauer data, Seebeck coefficients and activation energies lead to a m odel of both tetrahedral and octahedral conduction based on charge hopping. For F e1.gV 1. | 0 4 there exists only one iron species.
