One of the useful indices in molecular topology is Randić index. The alternative double bonds andconjugation in the polyene compounds are one of the main properties in these compounds. Someof the molecular orbital and structural properties refer to this specialty, such as: molar absorptioncoefficient (εmax) , electrical conductivity and difference energy level of the HOMO and LUMOorbitals, etc....

the reaction between ni(ii), co(ii), cr(iii) bitrates, ni(ii) chloride and ambidentate a-keto ylide benzoylmethylenetriphenylphosphine (bppy) resulted in isolation of [ni(bppy)2](no3)2.2h2o, [ni(bppy)2]cl2, [co(bppy)2](no3)2 and [cr(bppy)3](no3)3; 2h2o. the compounds were characterized by elemental analyses and infrared 1hnmr spectroscopy, molar conductivity in solution and molecular weight mea...

4(4-Nitrophenyl-zao)-2-(2-Methoxy phenimino)-phenol and its coordination compounds with Ni(II), Cu(II), Co(II) and Fe(III) have been synthesized and characterized by elemental analyses, FT-IR, Far-IR, Near IR, UV-Vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.

In this paper, we report the synthesis and characterization of a new symmetric macroacyclic Schiff base ligand (H2L) and related complexes with different metals. (H2L) was synthesized by the one pot condensation reaction of 2-[2-(2-formyl phenoxy)ethoxy]benzaldehyde and 2-aminobenzenethiol in a 1:2 molar ratio. The acyclic Schiff base was characterized by IR, NMR spectroscopy and elemental anal...

A new macrocyclic Schiff base complexes were prepared in the presence of lanthanide metal ion[La(III), Ce(III) and Gd(III)] by the reaction of 2,6 – diamino pyridine, benzoyl aceton and metal ion as template effect in the molar ratio of 2: 2: 1 respectively. The lanthanide metal complexes were characterized and investigated by using; 1 HNMR, FTIR, UV/Visible spectroscopy, Elemental analysis (C....

The present work reported density, viscosity, speed of sound, electrical conductivity and refractive index data of L-alanine in the aqueous solutions of 1-hexyl-3-methylimidazolium ibuprofenate at T= 298.15 K. Using the measured data, partial molar volume of transfer ( ), partial molar isentropic compressibility of transfer ( ), viscosity B-coefficient of transfer (∆traB), ion association const...

On the basis of a versatile mode-coupling theory (MCT) method developed in Paper I [C. Contreras Aburto and G. Nägele, J. Chem. Phys. 139, 134109 (2013)], we investigate the concentration dependence of conduction-diffusion linear transport properties for a symmetric binary electrolyte solution. The ions are treated in this method as charged Brownian spheres, and the solvent-mediated ion-ion hyd...

Synthesis of the tripyridyldiamine Bn-CDPy3, a chiral pentadentate ligand, and characterization of its low-spin Co(III) complex [Co(Bn-CDPy3)Cl]Cl2 by X-ray crystallography, 1H NMR, 13C NMR, IR and UV-vis spectroscopy as well as molar conductivity and mass spectrometry, is described.

The transport coefficients of three ionic liquids, lithium bromide ~LiBr!, rubidium bromide ~RbBr!, and molten silica (SiO2) are calculated by the mixture mode-coupling theory. The static partial structure factors required are obtained from the interionic interaction potential by the Ornstein– Zernike/hypernetted-chain integral equation. The anomalous pressure dependence of the transport proper...
