The title complex [Cu(C10H8N2)3][Fe(CN)5(NO)]·2CH3OH·H2O, consists of discrete [Cu(bpy)3](2+) cations (bpy is 2,2'-bipyridine), [Fe(CN)5NO](2-) anions and solvent mol-ecules of crystallization (two methanol mol-ecules and one water mol-ecules per asymmetric unit). The Cu(II) ion adopts a distorted octa-hedral environment, coordinated by six N atoms from three bpy ligands. The cation charge is b...

In the title salt, [Fe(3)(C(2)H(6)NS)(6)](ClO(4))(3), the trinuclear cation lies on a special position of site symmetry; the central Fe atom is coordinated by six thiol-ate groups from the two flanking fac-(S)-[Fe(C(2)H(6)NS)(3)] units. In the flanking units, the three C(2)H(6)NS groups each chelate to the metal atom. The cations inter-act with the perchlorate anions through weak N-H⋯O hydrogen...

In the title hydrated mol-ecular salt, [Fe(C12H8N2)3](C9H5N4O)2·0.5H2O, the water mol-ecule site is half-occupied. The Fe-N bond lengths within the octa-hedral tris-chelate [Fe(phen)3](2+) ion (phen is 1,10-phenantroline) are indicative of a low-spin d(6) electronic configuration for the metal ion. The C-N, C-C and C-O bond lengths in the polynitrile anions indicate extensive electronic delocal...

Three new cesium oxometallates with trigonal-planar [MO3]n− anions (M = Zn, Fe, B) were observed as products of reactions aimed at the formation of alkali metal suboxometallates A9MO4 (A = Rb, Cs; M = Al, Ga, In, Fe, Sc), or as decomposition products thereof. Cs4[FeO3], Cs4[ZnO3] and Cs3[BO3] crystallize with new structure types (Cs4[FeO3]: triclinic, space group P1̄, a = 7.0652(1), b = 7.125(1)...

In the crystal structure of the title compound, [Fe(3)(NCS)(6)(C(4)H(4)N(2))(8)](n), each iron(II) cation is coordinated by four N-bonded pyrimidine ligands and two N-bonded thio-cyanate anions in a distorted octa-hedral environment. The asymmetric unit consists of one iron cation located on a crystallographic center of inversion, as well as one iron cation, three thio-cyanate anions and four p...

A new pyridine-2,3,5,6-tetracarboxylato-bridged Fe(III) complex with a K+ counter ion, K[Fe(H2pdtc)2] (1), was prepared from the reaction of Fe2(SO4)3 · 7H2O, pyridine-2,3,5,6-tetracarboxylic acid and KOH under ambient conditions. The complex has been characterized by singlecrystal and powder X-ray diffraction, IR spectroscopy, TG analysis, elemental analyses, and magnetic measurements. Through...

In this work, we probe anion production upon electron interaction with Fe(CO)5 clusters using two complementary cluster-beam setups. We have identified two mechanisms that lead to synthesis of complex anions with mixed Fe/CO composition. These two mechanisms are operative in distinct electron energy ranges. It is shown that the elementary decomposition mechanism that has received perhaps the mo...

In the title complex, [Fe(C(2)O(4))(C(5)H(4)N(2)O(4))](n), the Fe(II) ion is coordinated by two oxalate anions and a pyrimidine-2-carb-oxy-lic acid ligand in a slightly distorted octa-hedral geometry. Each oxalate anion chelates to two Fe(II) ions, forming chains along the a axis. The chains are further connected by O-H⋯O and C-H⋯O hydrogen bonds, stabilizing the structure. An intra-molecular O...

Reject water, which is the liquid fraction produced after dewatering of anaerobically digested activated sludge on the municipal wastewater treatment plants (MWWTPs), contributes up to 80% of the nitrogen and phosphorus loads to the MWWTP. It was proposed to combine the removal of nitrogen from reject water using the sequential biooxidation of NH(4)(+) and bioreduction of NO(3)(-) with precipit...

[1] Ambient aerosol samples were collected over the Arabian Sea during the month of March of 1997, aboard the German R/V Sonne, as part of the German Joint Global Ocean Flux Study (JGOFS) project. This is the third study in a series of analogous measurements taken over the Arabian Sea during different seasons of the monsoon. Dichotomous high-volume collector samples were analyzed for ferrous ir...
