A moderately stable hexacoordinated sulfur(VI) compound with four different kinds of ligands, CF3SF2(CN)2C1, results when CF3SF4CI is reacted with (CH3)3SiCN. The latter compound also gives F2S(CN)2 and (CF3)2S(CN)2 with SF4 and (CF3)2SF2, respectively. These tetracoordinated suifur(IV) compounds decompose rapidly at 25 °C but are stable at lower temperatures. With OSCl2 and SC12, the white sol...

The crystal structure of the title compound, C(9)H(12)ClNTe, contains isolated mol-ecules with no close Te⋯Cl inter-molecular contacts and has the same composition as a previously published structure [Engman et al. (2004 ▶). Phospho-rus Sulfur Silicon Relat. Elem.179, 285-292]. However, in this case, the compound has crystallized in a centrosymmetric space group, unlike the previously published...

The title compound, {(C(10)H(10)S(8))[HgCl(3)]}(n), is a sulfur-rich charge-transfer compound in which C(10)H(10)S(8) (+) cations and HgCl(3) anions are assembled by S⋯S [3.371 (5)-3.588 (5) Å] and S⋯Cl [2.833 (4)-3.488 (4) Å] contacts, and by weak inter-molecular C-H⋯Cl hydrogen bonds, forming a two-dimensional wave-like structure. The two C atoms of the -CH(2)-CH(2)- group in one of the catio...

In phototrophic sulfur bacteria, sulfite is a well-established intermediate during reduced sulfur compound oxidation. Sulfite is generated in the cytoplasm by the reverse-acting dissimilatory sulfite reductase DsrAB. Many purple sulfur bacteria can even use externally available sulfite as a photosynthetic electron donor. Nevertheless, the exact mode of sulfite oxidation in these organisms is a ...

The increased rate of solubilization of sulfide ores of iron and copper caused by Thiobacillus ferrooxidans has been attributed either to direct action of the bacteria on the ore or to an indirect effect whereby the ferric ion is presumed to oxidize the ore and is returned to the active, oxidized state by the iron-oxidizing bacteria. Attempts by M. P. Silverman (3) to demonstrate that microbial...

Hydrogenase, purified to an average specific activity of 328 mumol of H2 evolved/(min X mg of protein) from Clostridium pasteurianum W5, was found to have 4-5 Fe and 4-5 labile sulfur atoms per molecule of 60,000 molecular weight, in contrast with earlier reports of 12 Fe per molecule. Displacement of the iron-sulfur cluster from hydrogenase by thiophenol in 80% hexamethyl phosphoramide:20% H2O...

in this research, zeolite-tio2 nanocomposite was prepared for degradation of dibenzothiophene as a typical aromatic organosulfur compound of transportation fuels.the synthesized tio2 was immobilized on the surface of clinoptilolite by solid state dispersion (ssd) method. the nanocomposite was then characterized by xrd, ftir, tem and sem techniques. photodegradation of dibenzothiophene in n-hexa...

After intravenous injection of S-adenosyl-L-homocysteine3H (homocysteine-labeled) into rats, less than 15% of the radioisotope was incorporated into protein methionine or excreted in the urine as oc-ketobutyrate. The remaining radioisotope was found associated with an unknown keto acid excreted in the urine. Intravenous injection of Sadenosyl-L-homocysteine-35S or S-adenosyl-3H-L-homocysteine (...

Rats were injected subcutaneously with a5S042and [I-t4Clascorbic acid. A compound was isolated from rat liver and spleen which had chromatographic properties identical to synthetic ascorbic acid 2-sulfate (AAS). This compound gave a positive methanolic FeCla reaction, contained radioactive sulfur, and on hydrolysis it degraded to ~sSO42 and il~C]ascorbic acid. The isolated compound possessed id...
