Pressure effects and Mössbauer spectroscopic studies on a 3D mixed-valence iron spin-crossover complex with NiAs topology.
A three-dimensional mixed-valence iron complex with NiAs-type topology, [(Fe(III)(3)O)Fe(II)(TA)(6)(H(2)O)(3)].(ClO(4))(2)(NO(3))(EtOH)(H(2)O)(2) (1, HTA = tetrazole-1H-acetic acid), shows spin-crossover behavior that was characterized via variable-temperature crystal structures, Mössbauer spectra and magnetic susceptibilities, the pressure effects on the transition behavior were also studied.

The biferrocene-based salt [Bifc]2[Ni(mnt)2]3 (Bifc = bis(isopropylthio)biferrocene; mnt = maleonitriledithiolate) contains a biferrocenium monocation and dication within the same crystal. The coexistence of Fe(3+) and mixed-valence Fe(2.5+), which resembles the valence state of magnetite, was confirmed by Mössbauer spectroscopy.

15 صفحه اولSynthesis and Spectroscopic Characterization of a Series of New Anthralin Derivatives and Their Corresponding Spiro-Hetherocycles
Several 10-substituted anthralins were readily prepared. Their oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gave the corresponding novel heteroatomic systems. All derivatives were fully characterized by IR, Mass and 1HNMR spectroscopy.
متن کاملTheoretical 57Fe Mössbauer spectroscopy: isomer shifts of [Fe]-hydrogenase intermediates.
Mössbauer spectroscopy is an indispensable spectroscopic technique and analytical tool in iron coordination chemistry. The linear correlation between the electron density at the nucleus ("contact density") and experimental isomer shifts has been used to link calculated contact densities to experimental isomer shifts. Here we have investigated relativistic methods of systematically increasing so...
