Mixed ligands biologically active complexes of cobalt(II), copper(II) and nickel(II) with nicotinoylhydrazine-derived ONO, NNO and SNO donor schiff-base ligands having the same metal ion but different anions such as sulphate, nitrate, oxalate and acetate have been synthesised and characterised on the basis of their physical, analytical and spectral data. In order to evaluate the role of anions ...

The asymmetric unit of the title compound, [Cd(NCS)2(CH3CN)] n , consists of one Cd(II) cation, two thio-cyanate anions and one aceto-nitrile ligand, all in general positions. The Cd(II) cation is coordinated by three N atoms of two thio-cyanate anions and one aceto-nitrile ligand, as well as three S atoms of symmetry-related thio-cyanate anions within a slightly distorted octa-hedral coordinat...

In capillary electrophoresis, the background electrolyte (BGE) composition is the key parameter for achieving the quantification of ions. This study is focused on the optimization of a BGE for anion separation (buffer, UV sensor, electroosmotic flow modifier and pH), and its application to whey anions. The quantification of chloride, sulfate, citrate and phosphate, was achieved with a relative ...

Metal chalcogenide semiconductor nanocrystals (NCs) are ideal inorganic materials for solar cells and biomedical labeling. In consideration of the hazard and instability of alkylphosphines, the phosphine-free synthetic route has become one of the most important trends in synthesizing selenide QDs. Here we report a novel phase transfer strategy to prepare phosphine-free chalcogenide precursors. ...

In the crystal structure of the title compound, [Mn(C(12)H(6)O(4))(C(10)H(8)N(2))](n), the Mn atoms are each coordinated by four O atoms of naphthalene-1,4-dicarboxyl-ate anions and two N atoms of two symmetry-related 4,4'-bipyridine ligands within a strongly distorted octa-hedra. Two of the O atoms originate from one naphthalene-1,4-dicarboxyl-ate anion, whereas the remaining two O atoms deriv...

Uptake of uranium (VI) ions using an anion exchanger resin, namely amberlite CG-400, was studied through this work in the presence of sulfate anions. Impact of various parameters including pH, contact time, initial concentration of uranium ions and intrusion with different anion contents (phosphate, chloride,sulfate, nitrate and fluoride) was examined on the sorption performance of the resin. A...

In the title compound, (C10H10N2S)2[NiCl4]Cl2, the Ni(2+) cation is tetra-hedrally coordinated by four chloride anions. Two 4,4'-sulfanediyldipyridinium cations and two non-coordinating chloride anions are connected via N-H⋯Cl hydrogen-bonding inter-actions into 20-membered rings, in the middle of which are situated the [NiCl4](2-) complex anions. These rings are stacked in the b-axis direction...

Seed mediated aqueous chemical growth (ACG) route was used for the growth of ZnO nanostructures on Si substrate in four different growth mediums. The growth medium has shown to affect the morphology and the size of the different nanostructures. We observed that the medium containing zinc nitrate anions yields the nanorods, in a medium containing zinc acetate anions nano-candles are obtained. Wh...
