In this paper, the electrochemical oxidation of three Pt(II) complexes containing pyrrole oxime (HL) having a general formula of [Pt(NH3)Cl(L)] (1), [Pt(L)(2)] (2), and K[PtCl2(L)] (3) has been investigated by in-situ spectroelectrochemistry in dimethylformamide (DMF). An irreversible metal-based oxidation process occurs during the anodic scan for each of the three complexes. The electronic absorption spectral changes indicate that all the three complexes generate similar Pt(IV) compounds and free ligand. Our experimental data is supported by quantum chemistry calculations utilizing density functional theory. In addition, the frontier orbital energy distributions indicate that electron densities are localized on mainly platinum atom.

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...
Spectroelectrochemical investigations of pyrimidine-2-thionato-bridged binuclear platinum(III) complexes Ozbek, Ozge; ÖZALP YAMAN, Şeniz; Özkan, İlker; Önal, Ahmet Muhtar; İŞÇİ, HÜSEYİN (2014-05-28) The electrochemical behavior of the binuclear platinum(III-III) complexes [Pt-2(C4H3N2S)(4)X-2] (C4H3N2S- = pyrimidine-2-thionate; X- = Cl--,Cl- Br--,Br- I-) have been studied by cyclic voltammetry and insitu spectroelectrochemistry in an acetonitrile-tetrabutylammonium tetrafluoroborate solventelectrolyte couple. An irreversible metal based reduction appears during the cathodic scan for each of the three complexes. The changes in UV-Vis spectra observed in-situ during the reductive electrolysis indicate th...
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...
In Situ Formed "Weakly Ligated/Labile Ligand" Iridium(0) Nanoparticles and Aggregates as Catalysts for the Complete Hydrogenation of Neat Benzene at Room Temperature and Mild Pressures Bayram, Ercan; Zahmakiran, Mehmet; Özkar, Saim; Finke, Richard G. (American Chemical Society (ACS), 2010-07-20) "Weakly ligated/labile ligand" nanoparticles, that is nanoparticles where only weakly coordinated ligands plus the desired catalytic reactants are present, are of fundamental interest. Described herein is a catalyst system for benzene hydrogenation to cyclohexane consisting of "weakly ligated/labile ligand" Ir(0) nanoparticles and aggregates plus dry-HCl formed formed in situ from commercially available [(1,5-COD)IrCl](2) plus 40 +/- 1 psig (similar to 2.7 atm) H(2) at 22 +/- 0.1 degrees C. Multiple control...
Spectroscopic modifications of Pippard relations: first-order and second-order phase transitions in NH4Cl Yurtseven, Hasan Hamit (2001-01-01) In this study we introduce the spectroscopic modifications of Pippard relations and apply them to the disorder-induced Raman modes of NH4Cl in the first-order (P = 0) and second-order (2.8 kbar) phase regions in this crystalline system. We obtain Linear variations of the specific heat C-p with out observed frequency shifts [(l/nu)(partial derivative nu/partial derivativeT)(p)] of those Raman modes studied for the first-order and second-order phase transitions in NH4Cl. This will be discussed in detail.
