Coordinative properties of the pyridine-2-carbaldehyde thiosemicarbazone ligand towards Ni(II)
Three crystal structures of Ni compounds containing bis(pyridine-2-carbaldehyde thiosemicarbazone)
ligand (HL), namely (pyridine-2-carbaldehyde thiosemicarbazonato)(pyridine-2-carbaldeyde thiosemicarbazone)
nickel(II) nitrate hydrate [Ni(HL)L][NO3]⋅(H2O) (1), bis(pyridine-2-carbaldehyde thiosemicarbazone)
nickel(II) dinitrate [Ni(HL)2][NO3]2⋅(2a), and bis(pyridine-2-carbaldehyde thiosemicarbazone)
nickel(II) dinitrate dihydrate [Ni(HL)2][NO3]2⋅2(H2O) (2b) are determined by X ray diffraction methods.
Comparative structural studies are carried out
Sol-gel routes for the preparation of heterogeneous catalysts based on Ru, Rh, Pd supported metals
Determination of uranium by reversed-phase high-performance liquid chromatography
In this paper a new chromatographic procedure is proposed;
this procedure is based on the separation and determination
of U02'+ as a neutral complex, using reversed-phase chromatography
and spectrophotometric detection. Examples of
chromatographic separation of UOZ2+a s a complex have been already reported, in most cases using TLC and paper chromatography
Behaviour of tetrahedral nickel-triosmium carbonyl cluster and its monosubstitued derivatives with group V donor ligands in high-performance liquid cromatography
The chromatographic behaviour of some monosubstituted derivatives of the tetranuclear cluster (Cp)NiOs3 (μH)3(CO)9 (Cp = cyclopentadienyl) with groupVdonorligands (benzonitrile tertiary phosphines, triphenylamine and triphenylstibine) is reported. In reversed-phase and adsorption liquid chromatography, the kind of the substituents strongly influences the retention volumes, the dimension of the whole cluster having less effect. Correlations of retention volumes with the nature of the substituents were found only for small of compound
