In the title compound, [Fe(C(12)H(10)N(2)O)(3)](ClO(4))(2), the metal center is coordinated by six N atoms from the three bidentate chelating ligands in a distorted octa-hedral coordination geometry, with overall formation of the meridional (OC-6-21) isomer. Inter-molecular O-H⋯O hydrogen bonds between the hydroxyl groups of the cation and the counter-anions form an infinite one-dimensional cha...

Complexes containing the anions of 5-benzoylamido-1,3,4-thiadiazole-2-sulfonamide and 5-(3-nitro-benzoylamido)-1,3,4-thiadiazole-2-sulfonamid as ligands, and V(IV); Cr(III); Fe(III); Co(II); Ni(II); Cu(II) and Ag(I) were synthesized and characterized by standard procedures (elemental analysis; IR, electronic, and EPR spectroscopy; TG, magnetic and conductimetric measurements). The original sulf...

In the title complex, [Fe(C(13)H(12)NO(2))Cl(2)(C(5)H(5)N)]·C(5)H(5)N, the iron(III) atom is six-coordinated by the N and O atoms from the Schiff base ligand, the N atom from a pyridine mol-ecule and two chloride anions in a distorted octa-hedral geometry. The crystal packing is stabilized by inter-molecular O-H⋯N hydrogen bonds and C-H⋯π inter-actions.

In the title salt, (C(5)H(14)N(2))[FeCl(4)(H(2)O)(2)], the Fe(II) cation is coordinated by four Cl(-) anions and two water mol-ecules in a distorted octa-hedral geometry. The piperazine ring adopts a normal chair conformation. Inter-molecular N-H⋯Cl, N-H⋯(Cl,Cl) and O-H⋯Cl hydrogen bonding is present in the crystal structure.

– We present direct experimental evidence of the formation of a superstructure on the (111) surface of a magnetite, Fe3O4 single crystal. The superstructure, which has a periodicity of 42A and three-fold symmetry, has been observed by means of STM and LEED. Under the correct conditions of oxygen pressure and sample anneal temperature, the superstructure is reproducibly formed throughout most of...

This study assessed the applicability of Fe-impregnated biochar derived from cattle manure (Fe-CMB) as an adsorbent for removing Sb(V) aqueous solutions and investigated adsorption mechanism. Fe-CMB was mainly composed C, O, Cl, Fe, Ca, P, onto identified using energy dispersive spectrometer Fourier transform infrared spectroscopy. reached equilibrium within 6 h, data a function time were well ...

The mineral surface structure and ions’ interaction were of significant interest to understanding dissolution reaction. In this study, X-ray photoemission spectroscopy combined with ICP emission spectrometer was used investigate the influence leaching reaction conditions 8 M dilute sulfuric acid 12 concentrated on chemical composition, (valence) state ion distribution Columbite-(Fe) (FeNb2O6). ...

The exploration of the FeF3/FeF2-Hamtetraz-HF system in dimethylformamide by solvothermal synthesis evidences two isostructural 3D hybrid fluoroferrates. They are prepared from the same starting mixture at two different synthesis temperatures: 120 °C for [Hdma]·(Fe4(II)Fe(III)F8(H2O)2(amtetraz)4) () and 140 °C for [Hdma]1.5·(Fe4.5(II)Fe0.5(III)F7(H2O)(HCOO)(amtetraz)4) (). Both compounds are ch...

It is now well established that incubation of mitochondria at pH 8 or higher opens up an electrophoretic anion transport pathway in the inner membrane. It is not known, however, whether this transport process has any physiological relevance. In this communication we demonstrate that anion uniport can take place at physiological pH if the mitochondria are depleted of matrix divalent cations with...

A series of porphyrin-based ionic complexes were prepared through the reaction two porphyrin precursors, 5,10,15,20-tetrakis(4-(2-pyridyl)phenyl)porphyrin H2TPhPyP (1) and trans-dihydroxo [5,10,15,20-tetrakis(4-(2-pyridyl)phenyl)porphyrinato]tin(IV) Sn(OH)2TPhPyP (2), with various acids (HCl, HNO3, CF3COOH, H2SO4, H2CO3, H3PO4). The characterized via elemental analysis, 1H nuclear magnetic reso...
