Fe absorption is affected by many dietary factors. The objective of the present study was to measure the effects of high v. low content of vitamin C, meat and phytic acid in whole diets with Fe-fortified bread on the efficacy of Fe absorption. Thirty-two healthy women with low Fe stores were randomised to three groups, each of which was given two of six test diets containing either low/high amo...

In the title mol-ecule, [Fe(C(5)H(5))(C(16)H(12)N)], the cyclo-penta-dienyl rings are approximately eclipsed and the inter-planar angle is 0.8 (7)°. The Fe atom is slightly closer to the substituted cyclo-penta-dienyl ring, with an Fe⋯centroid distance of 1.639 (2) Å, compared with 1.645 (2) Å for the unsubstituted ring. The C=N double bond is essentially coplanar with the substituted cyclo-pen...

High pressure Raman, IR and X-ray diffraction (XRD) studies have been carried out on C 70 (Fe(C 5 H 5) 2) 2 (hereafter, " C 70 (Fc) 2 ") sheets. Theoretical calculation is further used to analyze the Electron Localization Function (ELF) and charge transfer in the crystal and thus to understand the transformation of C 70 (Fc) 2 under pressure. Our results show that even at room temperature dimer...

In the title salt, [Fe(C(12)H(8)N(2))(3)][Fe(2)Cl(6)O], the ionic components are linked into a two-dimensional supra-molecular layer by two pairs of C-H⋯Cl hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.655 (4) and 3.498 (3) Å]. The salt is characterized as a mixed-valent Fe(II)-Fe(III) compound, in which an Fe(II) atom is coordinated by three phen ligands, formi...

The title structure, [Fe(2)(C(5)H(5))(2)(C(14)H(19)BBrN)], contains a chiral and asymmetrically 2,2''-disubstituted biferrocene designed as precursor for enanti-oselective non-C(2)-symmetric biferrocenyldiphosphine catalysts. The mean bond lengths in the biferrocene unit are Fe-C = 2.048 (10) Å and C-C = 1.427 (8) Å within the cyclo-penta-dienyl rings. The B-N bond lengths of the BH(3) protecte...

The asymmetric unit of the title compound, (C(14)H(34)N(2))[Fe(2)Cl(6)O], contains one complete cation, two half-cations and two anions. The two half-cations are completed by crystallographic inversion symmetry. The Fe(III) atoms adopt fairly regular FeCl(3)O tetra-hedral geometries, although the bridging Fe-O-Fe bond angles differ significantly in the two anions, which both adopt an eclipsed c...

Next to the monoclinic polymorph [Cheng et al. (2005 ▶). Acta Cryst. E61, m892-m894], the triclinic title compound, [Fe(4)(C(2)H(5)S)(2)(S(2))(CO)(12)], is the second known form of this composition. The structure is composed of an [Fe(2)(C(2)H(5)S)(S)(CO)(6)] subcluster, which is linked to its counterpart by an inversion centre located at the mid-point of the central disulfide bond. The Fe(2)S(...

chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the paleozoic granitic rocks of the canadian appalachians, have been analyzed by electron microprobe for major elements and by 57fe m?ssbauer spectroscopy for the coordination and oxidation state of fe. comparison of m?ssbauer fe3+/fe ratios obtained from chlorite and its host biotite indicates that c...

22 Humid tropical forests support large stocks of surface soil carbon (C) that exhibit high 23 spatial variability over scales of meters to landscapes (km). Reactive minerals and organo-metal 24 complexes are known to contribute to C accumulation in these ecosystems, although potential 25 interactions with environmental factors such as oxygen (O2) availability have received much less 26 attenti...
