Voltammetric determination of extreme standard Gibbs ion transfer energy

Hubert Girault, Astrid Johana Olaya Avendano, Fernando Cortes Salazar, Manuel Alejandro Méndez Agudelo

A voltammetric methodology to determine the standard Gibbs energy of transfer of highly hydrophobic and hydrophilic ions has been developed. The electrochemical cell used includes a water|1,2-dichloroethane micro-interface supported on a microhole in a thi ...

simple physical model for the simultaneous rationalisation of melting points and heat capacities of ionic liquids

Paul Joseph Dyson

The anal. of potential energy surfaces of ion pairs within the framework of an anharmonic oscillator model allows rationalization and prediction of m.ps. (Tmp) and heat capacities (Cp) of ionic liqs. (ILs) comprising di- and trialkylimidazolium or tetraalk ...

Separation of the Oxide and Halide Part in the Oxohalide Fe3Te3O10Cl Due to High Lewis Acidity of the Cations

Helmuth Berger, Dong Zhang

A new iron tellurite halide Fe3Te3O10Cl has been identified that crystallizes in the monoclinic space group P2(1)/c. The crystal structure comprises channels where the Cl ions and also the stereochemically active lone-pair electrons on Te4+ are located. Th ...

Synthesis, structures and characterisations of truly homoleptic acetonitrile Ln3+ complexes in solid state and in solution

Rosario Scopelliti, Lothar Helm, Ines Raabe, Gabriella Eva Bodizs

Total halide abstraction from LnCl3 by Ag[Al(OC(CF3)3)4]/CH3CN has been confirmed for a series of lanthanide metal ions by the structural characterization of [Ln(CH3CN)n][Al(OC(CF3)3)4]3 (n = 9, Ln3+ = Nd, Eu, Gd, Dy; n = 8, Ln3+ = Tm) complexes. Evidence ...

Comparison of two Metal Ion Implantation Techniques for Fabrication of Gold and Titanium Based Compliant Electrodes on Polydimethylsiloxane

Herbert Shea, Samuel Rosset, Muhamed Niklaus

This study contrasts the implantation of 25 μm thick Polydimethylsiloxane (PDMS) membranes with titanium and gold ions at 10 keV and 35 keV for doses from 1x10^15 at/cm2 to 2.5x10^16 at/cm2 implanted with two different techniques: Filtered Cathodic Vacuum ...

Ruthenium nanoparticles intercalated in hectorite: A reusable hydrogenation catalyst for benzene and toluene

Gabor Laurenczy, André Meister

The cationic organometallic aqua complexes formed by hydrolysis of [(C 6H6)RuCl2]2 in water, mainly [(C6H6)Ru(H2O)3]2+, intercalate into sodium hectorite by ion exchange, replacing the sodium cations between the anionic silicate layers. The yellow hectorit ...

Structure and characterization of CI3+[Al{OC(CF3)3}4]-; Lewis acidities of CX3+ and BX3

Ines Raabe, Nils Trapp

Prepn. of the title compd. (I) from starting materials CI4 and AgAl{OC(CF3)3}4 was performed with the complete exclusion of light and with carefully purified diiodine-free CI4, since CI4 decomps. within minutes in soln. in light with formation of I2 ...

Silver Complexes of a Novel Tripodal N-Heterocyclic Carbene Ligand: Evidence for Significant Metal-Carbene pi-Interaction

Xile Hu

A novel N-heterocyclic tridentate polycarbene ligand has been synthesized and stabilized as its corresponding silver complex. An electronic structure investigation reveals significant pi-bonding interactions within the Ag-carbene unit of the [(TIMEMe)2Ag3] ...

Approaching the gas-phase structures of [AgS8]+ and [AgS16]+ in the solid state

Isabelle Dionne

Upon treating elemental S with [AgSbF6], [AgAl(hfip)4], [AgAl(pftb)4] (hfip = OCH(CF3)2, pftb = OC(CF3)3), [Ag(S8)2][SbF6] (1), [AgS8][Al(hfip)4] (2), and [Ag(S8)2]+[Al(pftb)4]- (3) formed in SO2 (1), CS2 (2), or CH2Cl2 (3). 1-3 Were characterized by singl ...
