In the mol-ecule of the title compound, C(8)H(11)N(3)O(4)S, the thia-zine ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules.

Herein, a theoretical study on the stability of some vic-dioxime complexes of Ni(II), Pd(II) and Pt(II) in gas and aqueous phases is reported. The DFT/M06/SDD and DFT/M06/6-31G+(d,p) levels of theory were adopted for the metal ions and for every other element respectively. Structural analyses of investigated complexes have revealed square planar geometries stabilized by two O–H⋯Cl hydrogen bond...

The oxidation of hydrocarbons different structures under the same conditions is an important stage in study chemical properties both themselves and catalysts. In a 50% H2O2/Cu2Cl4·2DMG/CH3CN system, where DMG dimethylglyoxime (Butane-2,3-dione dioxime), at 50 °C or similar conditions, we oxidized eleven RH structures: mono-, bi- tri-cyclic, framework aromatic. To compare composition products th...

A new quinoxaline-substituted vicinal dioxime ligand containing bis(12-diazacrown-4) units (H2L) was synthesized by the reaction of cyanogen di-N-oxide with compound 4. Mononuclear Ni and Cu complexes with a metal: ligand ratio of 1:2 for H2L and a trinuclear Cu II complex were also synthesized. The mononuclear Cu species coordinated to two Cu ions through the deprotonated oximate oxygens to yi...

The resistance of Mycobacterium tuberculosis to isoniazid (INH) is largely linked to suppression of a catalase-peroxidase enzyme (KatG) that activates INH. In the absence of KatG, antioxidant protection is provided by enhanced expression of the peroxiredoxin AhpC, which is itself reduced by AhpD, a protein with low alkylhydroperoxidase activity of its own. Inhibition of AhpD might therefore imp...

The feasibility of using bis(delta2-2-imidazolinyl)-5,5'-dioxime (H2L) for the selective extraction of iron(III) from aqueous solutions was investigated by employing an solvent-extraction technique. The extraction of iron(III) from an aqueous nitrate solution in the presence of metal ions, such as cobalt(II), copper(II) and nickel(II), was carried out using H2L in binary and multicomponent mixt...
