Naturforsch. 34b, 712-715 (1979); received January 9, 1979 Semiquinone, Iron, Chromium Tris o-benzosemiquinone complexes of iron and chromium are reported. These complexes contain three 3,5-di-£-butyl-o-semiquinato ligands and a tri valent metal ion. The iron complex can be obtained f...

The present study aims to synthesis and full characterization of two new pentacoordinated isothiocyanate iron(III) mixed ligand complexes featuring dianionic (N2O2)2? tetradentate Schiff-base ligands unsymmetrically substituted by either a pair acceptor (4-fluorophenyl nitro) or donor (ferrocenyl methoxy) substituents. neutral complexes3 4 were prepared in very good yields (~90 %) upon reaction...

Chemodenitrification-the abiotic (chemical) reduction of nitrite (NO2?) by iron (II)-plays an important role in nitrogen cycling due part to this process serving as a source nitrous oxide (N2O). Questions remain about the fate NO2? presence mineral surfaces formed during chemodenitrification, such iron(III) (hydr) oxides, particularly relative dissolved iron(II). In study, stirred-batch kinetic...

OBJECTIVES The absorption of commonly used ferrous iron salts from intestinal segments at neutral to slightly alkaline pH is low, mainly because soluble ferrous iron is easily oxidized to poorly soluble ferric iron and ferrous iron but not ferric iron is carried by the divalent metal transporter DMT-1. Moreover, ferrous iron frequently causes gastrointestinal side effects. In iron(III)-hydroxid...
