The asymmetric unit of the title complex, [Cu(4)Fe(CN)(6)(C(6)H(18)N(4))(4)][Fe(CN)(5)(NO)](2)·6H(2)O, comprises a complex [{Cu(tren)CN}(4)Fe(CN)(2)](4+) [tren is tris-(2-amino-eth-yl)amine] cation, which exhibits -1 symmetry with the terminal cyanide ligands oriented trans to each other, and two [Fe(CN)(5)(NO)](2-) nitroprussiate counter-anions. In the crystal, N-H⋯N hydrogen-bonding inter-act...

A new {Fe(NO)(2)}(10) dinitrosyl iron complex possessing a 2,9-dimethyl-1,10-phenanthroline ligand has been prepared. This complex exhibits dioxygenase activity, converting NO to nitrate (NO(3)(-)) anions. During the oxygenation reaction, formation of reactive nitrating species is implicated, as shown in the effective o-nitration with a phenolic substrate.

The crystal structure of the title Fe(II) complex, [Fe(NCS)(2)(C(7)H(8)N(4)S)(2)(CH(3)CH(2)OH)(2)]·2C(7)H(8)N(4)S, based on the Schiff base ligand pyridine-3-carbaldehyde thio-semicarbazone (pct), results from the cocrystallization of an Fe(II) coordination compound together with two of the pct ligands. The complex unit is mononuclear, with the central Fe(II) ion located on a crystallographic c...

The title compound, [Co(C(10)H(8)N(2))(3)][Fe(C(2)O(4))(3)]·H(2)O, con-sists of two discrete tris-(chelate) metal ions (Co(III)N(6) and Fe(III)O(6) chromophores) and a water mol-ecule. The structure is highly symmetrical; the Co(III) and Fe(III) ions occupy positions with site symmetry 3.2. The coordination polyhedra of the metal atoms have a nearly octa-hedral geometry with noticeable trigonal...

In the title mol-ecular salt, (C(13)H(22)N)[FeCl(4)], three of the chloride ions of the tetra-hedral Fe(III)-containing anion are disordered over two orientations in a 0.656 (11):0.344 (11) ratio. In the crystal, there are no identifiable directional inter-actions between cations and anions except for Coulombic forces.

The title compound, [Ga(H(2)O)(6)](NO(3))(3)·3H(2)O, is isostructural to other known M(III) nitrate hydrates (M = Al, Cr, Fe). The structure contains two distinct octa-hedral Ga(OH(2))(6) units (each of symmetry) which are involved in inter-molecular hydrogen bonding with the three nitrate anions and three water mol-ecules within the asymmetric unit.

Imidazolium ionic liquids (ILs) exhibited a dramatic acceleration effect on the electron transfer from metal complexes such as (C(5)Me(5))(2)Fe(II) and (C(5)Me(5))(2)Co(II) to the oxygen molecule; this acceleration effect can be ascribed to the stabilization of the oxygen radical anions by coordinating with the acidic C2-H of imidazolium ILs.

Water is the most important resource of a country, and of the entire society as a whole, since no life is possible without water. It has this unique position among other natural resources, like minerals, fuels, forests, livestock etc. because a country can survive in the absence of any other resources, except this one.

a carbon ionic liquid electrode (cile) modified with tio2-fe nanoparticles was constructed by incorporating tio2-fe nanoparticles into the paste matrix. under the optimized experimental conditions, using differential pulse voltammetry (dpv), the oxidation of thiocyanate and oxalate were occurred at potentials of 0.740 v and 1.010 v, respectively, at the surface of the modified electrode. observi...

The title compound, [Fe(C(24)H(21)O(4)S(2))(2)(C(5)H(5)N)(2)], has 2 symmetry. The Fe(II) cation is located on a twofold rotation axis and is O,O'-chelated by two 2-{5-[(2-carb-oxy-phen-yl)sulfanylmeth-yl]-2,4-dimethyl-benzyl-sulfan-yl}benzoate anions and further coordinated by two pyridine ligands in a distorted octa-hedral geometry. In the anion, the terminal benzene rings are oriented at dih...
