A new magnetic-bottle time-of-flight photoelectron spectroscopy (PES) apparatus is constructed in our laboratory. The PES spectra of iron sulfide, hydrosulfide, and mixed sulfide/hydrosulfide [FeSm(SH)n-; m, n = 0-3, 0 < (m + n) ≤ 3] cluster anions, obtained at 2.331 eV (532 nm) and 3.492 eV (355 nm) photon energies, are reported. The electronic structure and bonding properties of these cluster...

The asymmetric unit of the title compound, [Fe(C(12)H(6)O(4))(C(10)H(8)N(2))], consists of two independent Fe(II) atoms, two naphthalene-1,4-dicarboxyl-ate anions and two 4,4'-bipyridine ligands. The Fe(II) atoms are each coordinated by four O atoms of the naphthalene-1,4-dicarboxyl-ate anions and two N atoms of the 4,4'-bipyridine ligands within a distorted octa-hedron. Two Fe(II) atoms are br...

In the title compound, {(C(12)H(12)N(2))[Fe(NCS)(4)]}(n), each Fe(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in an octa-hedral coordination mode. The asymmetric unit consists of one Fe(II) cation, located on a center of inversion, as well as one protonated (E)-4,4'-(ethene-1,2-di-yl)dipyridinium dication and two thio-cyanate anions in general positions. The ...

In the title compound, (C7H11N2)3[Fe(NCS)6]·H2O, the Fe(III) cation is coordinated by six terminal N-bonded thio-cyanate anions into a discrete threefold negatively charged complex. Charge balance is achieved by three protonated 4-(dimethyl-amino)-pyridine cations. The asymmetric unit consists of one Fe(III) cation, six thio-cyanate anions, three 4-(dimethyl-amino)-pyridinium cations and one wa...

In the crystal structure of the title compound, {(C(12)H(14)N(2))[Fe(NCS)(4)]}(n), the iron(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in a distorted octa-hedral coordination mode. The asymmetric unit consists of half an iron(II) cation and half a protonated (E)-4,4'-(ethane-1,2-di-yl)dipyridinium dication, each located on a centre of inversion. In addition,...

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...

In the title complex, [Fe(2)Cl(2)(C(11)H(16)N(4))(4)][FeCl(4)](2), the asymmetric unit is composed of one and a half units of [Fe(bdmpm)(2)Cl](2)(FeCl(4))(2)(bdmpm = bis(bis(3,5-dimethyl-pyrazol-1-yl)methane). The three independent Fe(II) atom have a distorted octa-hedral coordination geometry comprising two bridging chloride anions and four N atoms from two bis-(3,5-dimethyl-pyrazol-1-yl)metha...

Polymeric phosphate aluminum-ferric chloride (PPAFC) in this study was prepared. In order to obtain the optimum conditions for preparation of PPAFC, resulting in a better turbidity removal efficiency, parameters such as the molar ratio of Al/Fe, P/(Al+Fe), OH/(Al+Fe) as well as the reaction temperature were examined. Results showed that the optimal synthetic conditions were Al/Fe of 6:4, P/(Al+...

The asymmetric unit of the title compound, [Fe4(C6H6O4S2)2(C10H15)2S4]PF6, contains two different complex cations and two PF6 (-) anions. The two complex cations have similar conformations with the butterfly-like Fe4S4 core surrounded by two penta-methyl-cyclo-penta-dienyl ligands and the S atoms of two dithiol-ate ligands. In each Fe4S4 core, there are four short Fe-Fe and two long Fe⋯Fe conta...

In the title compound [Fe(NCS)2(C8H6N4S)2(H2O)2]·H2O, the Fe(II) cation is coordinated by two N-bonded thio-cyanate anions, two N (4)-bonded bis-(pyrazin-2-yl) sulfide ligands and two water mol-ecules in an slightly distorted octa-hedral geometry. The Fe(II) cation is located on a center of inversion and the lattice water mol-ecule on a twofold rotation axis. The thio-cyanate anions, the coordi...
