In the title compound, (NH(4))(2)[Fe(C(10)H(12)N(2)O(8))(H(2)O)]·3H(2)O, the Fe(II) center is in a distorted penta-gonal-bipyramidal geometry. Two carboxyl-ate O and two N atoms from the ethyl-enediaminetetra-acetate (EDTA) ion and one O atom from coordinated water comprise the equatorial plane. Two other carboxyl-ate O atoms from the EDTA ion occupy the apical sites. Both ammonium cations and ...

The search for new mol-ecular materials with inter-esting magnetic properties using the pseudohalide azide ion and quinolin-8-amine (aqin, C9H8N2) as a chelating ligand, led to the synthesis and structure determination of the title complex, [Fe(N3)2(C9H8N2)2]. The complex shows an octa-hedral geometry, with the FeII atom surrounded by six N atoms; the two N3- anions coordinate in a cis configur...

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. Observ...

In the title compound, [Fe(C(38)H(38)N(10))](ClO(4))(2)·CH(3)OH, the Fe(II) atom has a distorted octa-hedral coordination environment with four benzimidazol N atoms and two amino N atoms from an N,N,N',N'-tetra-kis-(benzimidazol-2-ylmeth-yl)cyclo-hexane-1,2-trans-diamine ligand. The uncoordinated solvent methanol mol-ecule is hydrogen bonded to an O atom of a perchlorate anion. One of the perch...

HE WATER quality characteristics and some heavy metals cations (Fe, Mn, Zn, Cu and Pb) of Damietta estuary and in front of Mediterranean coastal shoreline were evaluated through four successive cruises (February 2008 to November 2008). Twelve sites were selected from the two sectors. The results obtained showed that serious deterioration of quality of water at Damietta estuary compared with Med...

The asymmetric unit of the title complex, [Fe2Ni(C19H12N3O)2(CN)6(C16H36N4)]·2.07H2O, contains one [Fe(qcq)(CN)3](-) anion, half a [Ni(teta)](2+) cation and two partially occupied inter-stitial water mol-ecules [qcq(-) is the N-(quinolin-8-yl)quinoline-2-carboxamidate anion and teta is 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne]. In the complex mol-ecule, two [Fe(qcq)(CN)...

The asymmetric unit of the title compound, (C(13)H(11)N(2))[Fe(C(7)H(3)NO(4))(2)]·4H(2)O, contains a 9-amino-acridinium cation, one anionic complex and four uncoordinated water mol-ecules. In the anionic complex, the Fe(III) ion is six-coordinated by two almost perpendicular [dihedral angle = 88.78 (7)°] pyridine-2,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, an...

This paper explains a new procedure for flow injection analysis (FIA) determination of iron in rain water based on the colour reaction of Fe(3+) with thiocyanate ions in the presence of the cationic surfactant cetylpyridinium chloride (CPC). The value of apparent molar absorptivity of the complex in terms of iron is (2.00) x 10(4) l mole(-1) cm(-1) at an absorption maximum of 490 nm. The detect...

In the title compound, {[Fe(CHO(2))(2)(C(10)H(8)N(2))(H(2)O)]·4H(2)O}(n), the Fe(II) ion is coordinated by two 4,4'-bipyridyl (4,4'-bpy) ligands, three formate ligands and one water molecule. The slightly distorted octahedral FeN(2)O(4) coordination results from the N atoms of two bridging 4,4'-bpy ligands, the O atoms of two bridging HCOO(-) anions of anti-anti mode, all in trans positions aro...
