The title compound, (CH(6)N(3))[Zn(2)(C(7)H(3)NO(5))(2)(C(7)H(4)NO(5))(H(2)O)]·2H(2)O, has an anionic binuclear complex of Zn(II) balanced with a guanidinium cation. There are two uncoord-inated water mol-ecules in the structure. The asymmetric unit of the compound has two different coordination types (the coordination of Zn1 is distorted trigonal-bipyramidal, while that of Zn2 is distorted oct...

Data presented in this paper describe how the percentage decomposition of the catalase-H202 intermediate by methanol and ethanol as determined from absorbance changes (660 to 640 nm) through a lobe of the perfused rat liver can be used to calculate the intracellular ethanol concentration. Values obtained were similar to those measured in the eftluent fluid from the liver. Using this technique, ...

In the title compound, tetra-kis[μ(3)-(2-pyrid-yl)methano-lato]tetra-kis[bromido(methanol)cobalt(III)] tetra-bromide 2-(hydroxy-meth-yl)pyridine tetra-solvate dihydrate, [Co(4)Br(4)(C(6)H(6)NO)(4)(CH(3)OH)(4)]Br(4)·4C(6)H(7)NO(4)·2H(2)O, the cation comprises a [Co(4)O(4)] cubane-type core ( symmetry). The four Co(III) ions and bridging O atoms from four (2-pyrid-yl)methano-late anions are locat...

In the title compound, [CoCl(2)(C(13)H(9)Cl(2)N(3)O(2))(2)(C(12)H(8)N(2))]·CH(3)OH, the Co(II) atom is octahedrally coordinated by two N atoms from the pyridyl rings of the tridentate N'-(3,5-dichloro-2-hydroxy-benzyl-idene)pyridine-4-carbohydrazide (H(2)L) ligand, two N atoms from the 1,10-phenanthroline ligand and two chloride ions. The acyl-hydrazone groups are not involved into the coordina...

The presence of nicotine and nicotinic acid (NA) in the marine environment has caused great harm to human health and the natural environment. Therefore, there is an urgent need to use efficient and economical methods to remove such pollutants from the environment. In this study, a nicotine and NA-degrading bacterium-strain JQ581-was isolated from sediment from the East China Sea and identified ...
