The asymmetric unit of the title compound, [Mn(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, consists of a complex [Mn(C(8)H(7)N(3))(3)](2+) cation, half of a mixed-valent Mo(V,VI) α-Keggin-type [PMo(12)O(40)](4-) heteropolyanion, and three uncoordinated water mol-ecules. The Mn(2+) cation is surrounded by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands in a distorted octa-hedr...

In situ rates of reductive dissolution in submerged shoreline sediments at Lake Tegel (Berlin, Germany) were measured with a novel hydrous manganese (Mn) oxide-doped gel probe sampler in concert with equilibrium gel probe and sequential extraction measurements. Rates were low in the top 8 cm, then showed a peak from 8 cm to 14 cm, with a maximum at 12 cm depth. This rate corresponded with a pea...

In the title compound, [Mn(2)(C(8)H(3)NO(6))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)], the Mn(II) atom in the centrosymmetric binuclear unit has a distorted octa-hedral geometry and is coordinated by a chelating 1,10-phenanthroline ligand, two monodentate carboxyl-ate anions from two 4-nitro-phthalates and two coordinated water mol-ecules. The two Mn(II) ions in the mol-ecule are bridged by two 4-nitro-...

Temporal pattern of expression of Cu/Zn and Mn superoxide dismutases (SODs) was investigated in bovine oocytes and embryos produced in vitro in two different culture conditions and in vivo after superovulation. SODs were examined at a transcriptional level in single oocytes and embryos by reverse transcriptase-polymerase chain reaction (RT-PCR) and, at a protein level, by Western blotting on po...

Manganese-salen complexes (Mn-Salen), including EUK-8 [manganese N,N'-bis(salicylidene)ethylenediamine chloride] and EUK-134 [manganese 3-methoxy N,N'-bis(salicylidene)ethylenediamine chloride], have been reported to possess combined superoxide dismutase (SOD) and catalase mimetic functions. Because of this SOD/catalase mimicry, EUK-8 and EUK-134 have been investigated as possible therapeutic a...

The title complex, {[Mn(C(14)H(8)O(4)S(2))(C(12)H(8)N(2))(2)]·0.5CH(3)OH·H(2)O}(n), has a one-dimensional chain structure in which the Mn(II) atom is six-coordinated by four N atoms from two 1,10-phenanthroline (phen) ligands and two O atoms from two 2,2'-dithio-dibenzoate (L) ligands. The L ligands adopt a bis-(monodentate) (syn-anti) coordination mode and bridge adjacent Mn(II) centres, gener...

The centrosymmetric binuclear title complex, [Mn(2)(C(8)H(5)NO(5))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, was obtained by the reaction of manganese chloride with 5-carb-oxy-1-carboxy-methyl-2-oxidopyridinium and 1,10-phenanthroline. The Mn(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium ligan...

BACKGROUND & AIMS Manganese (Mn) deposition could be responsible for the T(1)-weighted magnetic resonance signal hyperintensities observed in cirrhotic patients. These experiments were designed to assess the regional specificity of the Mn increases as well as their relationship to portal-systemic shunting or hepatobiliary dysfunction. METHODS Mn concentrations were measured in (1) brain sampl...

The title compound, [Mn(C(8)H(7)N(3))(3)](2)[SiMo(12)O(40)]·6H(2)O, consists of an [SiMo(12)O(40)](4-) heteropolyanion, lying on a centre of inversion, and a complex [Mn(C(8)H(7)N(3))(3)](4+) cation. The Mn(II) atom of the cation is hexa-coordinated in a distorted octa-hedral geometry by six N atoms from three chelating 3-(2-pyrid-yl)pyrazole ligands. In the heteropolyanion, the four O atoms of...

In the centrosymmetric dinuclear title complex, [Mn(2)(C(16)H(10)NO(2))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the Mn(II) cation is in a distorted octa-hedral coordination geometry defined by two N atoms from a 1,10-phenanthroline ligand, one water O atom and three O atoms from three 2-phenyl-quinoline-4-carboxyl-ate anions. A pair of 2-phenyl-quinoline-4-carboxyl-ate anions bridge two Mn cati...
