The electrochemical behaviour of Na(Et2NCS2) and M(Et2NCS2)(2) (M = NI(II), Pd(II) and Pt(II): Et2NCS2-= diethyldithiocarbamate) as studied by cyclic voltammetry in the acetonitrile-(n-Bu)(4)NBF4 solvent-electrolyte couple at room temperature vs. Ag/Ag+ reference electrode. Constant potential electrolyses of the complexes were carried out at their first oxidation peak potentials and monitored in situ by UV-VIS spectrophotometry. The electrolysis of Ni(Et2NCS2)(2) in solution yielded the dimer of the ligand, (Et2NCS2)(2), and Ni2+(sol) as final products. During this electrochemical process the formation of a Ni(III) complex species as an intermediate has been observed. The electrochemical oxidation of bis(diethyldithiocarbamato) complexes of Pd(II) and Pt(II) yielded [Pd(Et2NCS2)(3)](+) and [Pt(Et2NCS2)(3)](+), respectively.

Spectroelectrochemical investigation of pentacarbonyl(pyrazine)metal(0) (metal = Cr, Mo, W) complexes of group 6 elements Yaman, SO; Nalbant Esentürk, Emren; Kayran, C; Önal, Ahmet Muhtar (2002-01-01) The electrochemical behaviour of pentacarbony l(pyrazine) metal (0) complexes of the group 6 elements was studied by cyclic voltammetry in dichloromethane-(n-Bu)(4)NBF4 solvent-electrolyte couple at -20 degreesC vs. Ag/Ag+ or SCE reference electrode. Constant potential electrolyses of the complexes were carried out at their first oxidation peak potentials and monitored in situ by UV-Vis spectrometry. Electrolysis of W(CO)(5)pz produces [W(CO)(5)pz](+) and a similar electrochemical mechanism is expected both...
Electrochemical behaviour and electrochemical polymerization of fluoro-substituted anilines Cihaner, A; Önal, Ahmet Muhtar (2002-08-01) The electrochemical behaviour of three fluoro-substituted aniline monomers, 2-fluoroaniline (2FAN), 3-fluoroaniline (3FAN) and 4-fluoroaniline (4FAN), was investigated in aqueous acidic and organic media by means of cyclic voltammetry (CV) studies. Constant potential electrolysis (CPE) of the monomers in acetonitrile-water mixture (1: 1 by volume) using NaClO4 as supporting electrolyte yielded soluble polymers. The mechanism of electrochemical polymerization was investigated using in situ electron spin reso...
Spectroelectrochemistry of potassium ethylxanthate, bis(ethylxanthato)nickel(II) and tetraethylammonium tris(ethylxanthato)nickelate(II) Dag, O; Yaman, SO; Önal, Ahmet Muhtar; Isci, H (2001-10-07) Electrochemical and chemical oxidation of S2COEt-, Ni(S2COEt)(2), and [Ni(S2COEt)(3)](-) have been studied by CV and in situ UV-VIS spectroscopy in acetonitrile. Cyclic voltammograms of S2COEt- and Ni(S2COEt)(2) display one (0.00 V) and two (0.35 and 0.80 V) irreversible oxidation peaks, respectively, referenced to an Ag/Ag+ (0.10 M) electrode. However, the cyclic voltammogram of [Ni(S2COEt)(3)](-) displays one reversible (- 0.15 V) and two irreversible (0.35, 0.80 V) oxidation peaks, referenced to an Ag/Ag...
SOLID-STATE SYNTHESIS, STRUCTURE, AND VIBRATIONAL-SPECTRA OF NAGDP2O7 KIZILYALLI, M; DARRAS, M (Elsevier BV, 1993-12-01) NaGdP2O7 was synthesized by the solid-state reaction of Gd2O3 with Na2CO3 and 4(NH4)2HPO4 at 650°C. The X-ray powder diffraction data of NaGdP2O7 was indexed in the orthorhombic system with the approximate unit cell dimensions of a = 12.44 , b = 15.00, and c = 15.87 Å and the space group is Pmm2. Analysis of the vibrations of the P2O4-7 ion according to C2v symmetry and approximate band assignments for IR spectra are also reported in this work. The P-O-P band was found to be nonlinear, and some coincidences...
Spectroelectrochemical investigation of the anodic oxidation of dibenzo-18-crown-6 Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2004-10-01) Poly(dibenzo-18-crown-6) (poly-DB18C6) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as the solvent and tetrabutylammonium tetrafluoroborate (TBABF(4)) or tetrabutylammonium hexafluorophosphate (TBAPF(6)) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in situ ESR and in situ UV-Vis spectroscopic techniques. Spectroelectrochemical (SPEL), properties and thermal analysis of the resulting po...
