The hydrothermal reaction of K(3)[Fe(CN)(6)], CuCl(2), and 2,2'-bipyridine (bipy) resulted in the formation of a 2D cyanide-bridged heterobimetallic Fe(II)-Cu(I) complex, [Fe(bipy)(2)(CN)(4)Cu(2)], 1. Working in the same conditions, but using 2,2'-bipyrimidine (bpym) instead of bipy and methanol as solvent, we obtained the homometallic Cu(I) complex [Cu(2)(CN)(2)(bpym)](2), 2. The structure of ...

Ferrate (Fe(VI), K2FeO4) has attracted much attention in water treatment for its high redox potential, especially under acidic conditions. Although interests have been arising the performance of Fe(VI) at pH below 7.0, a contradicting trend second order reaction rates (kapp) was observed conditions, and reactive species (i.e., high-valent iron or hydroxyl radicals (HO•)) oxidation remains uncle...

The title compound, [Fe(C(17)H(16)N(2)O(2))(C(3)H(4)N(2))(2)]ClO(4), consists of monomeric [Fe(salmen)(HIm)(2)](+) cations {salmen is the 2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphen-olate dianion and HIm is 1H-imiazole} and perchlorate anions. In the cation, the Fe(3+) ion is octahedrally coordinated by two N atoms and two O atoms from a tetra-dentate salmen anion and two N atoms fro...

The title compound, {[Fe(NCSe)2(C12H12N2)(H2O)2]·2C12H12N2·2H2O} n , was obtained by the reaction of iron(II) sulfate hepta-hydrate and potassium seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) in water. The Fe(II) cation is coordinated by two N-bonded seleno-cyanate anions, two water mol-ecules and two 1,2-bis-(pyridin-4-yl)ethane (bpa) ligands in a slightly distorted octa-hedral geomet...

Four new Fe(II) coordination polymers of formulation [Fe(L)(3)][MCl(4)](2), M = Fe(III), In(III) have been synthesized and structurally and magnetically characterized. They contain organodinitrile bridging ligands where L is 1,1'-azobiscyclopentanecarbonitrile (ACCN) or 2,2'-azobisisobutyronitrile (AIBN). The compounds are [Fe(AIBN)(3)][InCl(4)](2) (1), [Fe(AIBN)(3)][FeCl(4)](2) (2), [Fe(ACCN)(...

The impact of ordered vacancies on the dynamic stability perovskites is investigated under $\textit{ab initio}$ framework with a focus cubic BaFeO$_{3}$ ($Pm\bar{3}m$) and vacancy-ordered monoclinic BaFeO$_{2.67}$ ($P2_{1}/m$). harmonic approximation shows that both structures are dynamically unstable at 0 K. For structure, instability related to rotational distortions Fe coordination tetrahedr...

We report a cathodoluminescence (CL) and x-ray photoelectron spectroscopy (XPS) study of the formation calcium vacancies (VCa) hydroxyl ion (VOH) in hydroxyapatite (HAp) nanobelts selectively doped with Fe3+ ions by substituting Ca(II) HAp lattice. Additionally, we paramagnetic behavior Fe concentrations lower than 1 atomic percent (at.%), besides absence superparamagnetism even at around 12 at...

Iron deficiency in dwarf bean (Phaseolus vulgaris L.) induces an increased activity of a system in the rhizodermal cells, which reduces extracellular ferric salts, and an active proton efflux from the roots, which is coupled to accumulation of citrate and malate in the roots and subsequent export of these compounds in the xylem. During reduction of extracellular ferricyanide by Fe-deficient pla...

The kinetics and mechanism for degradation of omethoate (OMT) by catalytic ozonation with Fe(III)-loaded activated carbon (Fe@AC) were investigated in this study with focus on identification of degradation byproducts. The rate constants of OMT reacting with ozone and hydroxyl radical ((·)OH) were determined to be 0.04 and 5.3×10(8) M(-1) s(-1) at pH 7.5 and 20 °C, respectively. OMT was predomin...
