In this work, a mixed-ligand copper complex, [Cu2(PPh3)4(μ-N3)2] (1), was prepared and identified by elemental analysis, molar conductivity, FT-IR, Raman, 1H NMR, 13C NMR and UV-Vis spectroscopy and single-crystal X-Ray diffraction. The copper atom in 1 which is coordinated by two nitrogen atoms of the two azide groups and two phosphorus atoms of the two triphenylphosphine groups has a distorte...

Abstract:With glucose as the starting material, sodium tripolyphosphate as the phosphorus acylating agent, and urea as the catalyst, glucose 1-phosphate was synthesized and its properties were analyzed. The synthesis conditions were selected according to the phosphorus content and optimized through the response surface methodology (RSM), based on a 3-level, 3-variable Box–Behnken experimental d...

A complex of neodymium(III) with 4-hydroxy-3[1-(4-nitrophenyl)-3-oxobutyl]-2H-1-benzopyran-2-one (acenocoumarol) was synthesized by mixing water solutions of neodymium(III) nitrate and the ligand (metal to ligand molar ratio of 1:3). The complex was characterized and identified by elemental analysis, conductivity, IR, 1H NMR and mass spectral data. DTA and TGA were applied to study the composit...

Ion association of the ionic liquid [bmim][Cl] in acetonitrile and in water was studied by dielectric spectroscopy for salt concentrations c r 1.3 M at 298.15 K and by measurement of molar electrical conductivities, L, of dilute solutions (c r 0.006 M) in the temperature range 273.15 t T/K r 313.15. Whilst acetonitrile solutions of [bmim][Cl] exhibit moderate ion pairing, with an association co...

Novel Mannich base derivatives of Benzimidazole were prepared through the condensation reaction of benzimidazole derivative with formaldehyde and primary and/ secondary amine. Zinc(II), copper(II), nickel(II) and cobalt(II) complexes of Mannich bases have also been synthesized. All the compounds were fully characterized by, elemental analyses, magnetic moment determination, molar conductivity m...

Electrolytes of a room temperature ionic liquid (RTIL), trimethyl(isobutyl)phosphonium (P111i4) bis(fluorosulfonyl)imide (FSI) with a wide range of lithium bis(fluorosulfonyl)imide (LiFSI) salt concentrations (up to 3.8 mol kg(-1) of salt in the RTIL) were characterised using a combination of techniques including viscosity, conductivity, differential scanning calorimetry (DSC), electrochemical ...
