    (Izmir Institute of Technology, 2009) Öcal, Jale; Topaloğlu Sözüer, Işıl
    Reactions of the dioxomolybdenum(VI) compound, MoCl2O2 with phenylenediamine derivatives the bidentate N-N nitrogen ligands 1-8 (ophenylenediamine, N-phenyl-o-phenylenediamine, 4-Methyl-o-phenylenediamine, 4-Nitro-o-phenylenediamine, p-phenylenediamine, N-phenyl-p-phenylenediamine, 2,6- dichloro-p-phenylenediamine, 2,3,5,6-tetramethyl-p-phenylenediamine, respectively) have been examined under nitrogen in THF solution. The novel dioxomolybdenum complexes were characterized by elemental analysis, FT-IR, 1H-NMR and 13C-NMR spectroscopy. In addition, molecular mechanics and quantum chemical calculations including semi empirical PM3 and DFT methods were carried out to discuss the stability of the compounds.

    Oxo-Imido molybdenum tripyrazolyl borate complexes
    (Izmir Institute of Technology, 2004) Günyar, Alev; Topaloğlu Sözüer, Işıl
    Reaction of the oxo-molybdenum(V) compound, [MoTp*(O)Cl2], [Tp* = hydrotris(3,5-dimetylpyrazol-1-yl)borate] with p-functionalized anilines[NH2C6H4R] ( R = OMe, OEt, OPr, NO2) in the presence of Et3N under nitrogen, in toluene solution, afforded the novel oxo bridged oxo(arylimido) molybdenum(V) compounds [MoTp*(O)Cl](m-O)[MoTp*(Cl)(ºNC6H4R)] ( R = OMe, OEt, OPr, NO2). Under same conditions, the reaction with aniline produced oxo bridged oxomolybdenum (V) compound, [MoTp*OCl]2(m-O). The new compounds were characterized by FT-IR, FAB-Mass, and 1H-NMRspectra. The single crystal X-ray crystallographic determination of [MoTp*(O)Cl](mO)[MoTp*(Cl)(ºNC6H4OMe)]was carried out to confirm that there is a Mo-O-Mobridge and a near linear arylimido group in the structure.

    Synthesis, Characterization and Computational Studies of Oxomolybdenum Compounds With Nitrogen Donor Ligands
    (Izmir Institute of Technology, 2010) Kıyak, Harika; Topaloğlu Sözüer, Işıl
    In the first part of the project, the reactions of the solvent-stabilized compound [MoO2Cl2(THF)2] with varios phenylenediamine and some napthalenediamin derivatives in THF at room temperature were investigated. These reactions yielded mononuclear and dinuclear compounds of the type [MoO2Cl2L] and [Mo2O3(.2- O)Cl4(L)2] respectively. In the second part, the reactions of [Mo2O3Cl4(DMF)4] with phenylenediamine and napthalenediamin derivatives were studied under similar conditions and Mo-O-Mo bridged dinuclear oxomolybdenum compounds of the type [Mo2O3(.2-O)Cl4(L)] were obtained. The new compounds were comparatively examined by elemental analysis, FTIR, 1H-NMR and 13C-NMR techniques. In addition, quantum chemical calculations including semi empirical PM3 and DFT methods were carried out to discuss the stability and geometry of the compounds.

    Synthesis, Characterization and Reactivity of [exo-Nido 9h10me2)]
    (Marcel Dekker Inc., 1996) Topaloğlu, Işıl
    In this work, the reaction of the 16-electron species [Rh(η3-C8H13)-(η5-C 2B9H9Me2)] with PPh3 was investigated and the product, [exo-nido-Rh-(PPh3)2(η5-C2B 9H10Me2)], which is in an equilibrium with the closo analogue was characterized by 31p{1H}, 1H, 13C and 11B NMR spectroscopy. A mechanism for the complex formation is suggested which is related to the previously reported reactions between the 16-electron complex and PR3 (R = Me and Et) ligands.

    Reactions of the Solvent-Stabilized Compound [moocl2(thf)2] With Aromatic Nitrogen Donor Ligands: Spectroscopic Characterization and Semiempirical Am1* Calculations
    (TUBITAK, 2009) Kılıçkaya, Gülşah; Doğan, Başak; Acar, Nursel; Sözüer, Hikmet Işıl
    Reaction of the solvent-stabilized dioxo-molybdenum(VI) compound [MoO2 Cl2 (THF)2]withP Ph3 yielded the oxomolybdenum(IV) species [MoOCl2 (THF)2](1) by the removal of one oxygen atom as PPh3 O. The complexes [MoOCl2 (=NC6 H4 CN)] 2,[MoOCl2 (CNC6 H4 OH)] 3,[MoOCl2 (=NC6 H4 NH2)] 4,and [MoOCl2 (=NC6 H4 OCH3)] 5, were synthesized by the reactions of [MoOCl2 (THF)2]with XC6 H4 Y(X =NH2, Y = CN; X= CN, Y = OH; X = Y = NH2;X=NH2,Y=OCH3). All the new compounds were characterized by elemental analyses, and FTIR, UV-Vis, and 1 H and 13 C-NMR spectra. Geometrical parameters and molecular orbital calculations showed that compounds 2-5 are stabilized by a charge transfer between the Mo center and the phenyl ring.

    Characterization of a Novel Dioxomolybdenum Complex by Cyclic Voltammetry
    (Taylor and Francis Ltd., 2015) Knittl, Esther Theresa; Rusakov, D. A.; Korotkova, E. I.; Dorozhko, E. V.; Voronova, O. A.; Plotnikov, E. V.; Topaloğlu Sözüer, Işıl; Linert, Wolfgang
    Metalloenzymes that carry a pterin-based molybdenum cofactor in their center catalyze numerous reactions in the human body and play a crucial role in its metabolism. Specifically, these enzymes promote redox reactions and oxygen transport in the body. Their absence may cause many problems leading to disability or even death in early childhood. Therefore, model compounds need to be synthesized and analyzed to investigate the reactivity, redox potential, and geometry of these cofactors. This study focused on electrode processes and determined the redox potentials of the new bis-(4-mercapto-5-(p-tolyl)-3H-1,2-dithiole-3-thione)-dioxomolybdenum complex by cyclic voltammetry. The 4-mercapto-5-(p-tolyl)-3H-1,2-dithiole-3-thione ligand underwent irreversible oxidation and reduction at thiol and thione functional groups. The new dioxomolybdenum complex showed a quasi-reversible two-stage electrode process.

    Oxo-Bridged (haloarylimido)[tris(3,5-Dimethylpyrazolyl)borato] Molybdenum(v) Complexes: Crystal Structures of Geometric Isomers of [motp*(o)cl](µ-O)[motp*(cl)(?nc6h 4br)]
    (De Gruyter, 2005) Sözüer, Hikmet Işıl; Dülger İrdem, Seçkiner; Jeffery, John J.; Hamidov, Hayrullah; Şentürk, Ozan Sanlı
    The reaction between [MoTp*(O)Cl2], [Tp* = hydrotris(3,5-dimetylpyrazol-1-yl)borate] and 4-bromoaniline in refluxing toluene gave geometric isomers of [MoTp*(O)Cl](μ-O)[MoTp*(Cl) (≡NC6H4Br)] (1a, cis; 1b, trans), but a similar reaction between [MoTp*(O)Cl2] and 4-chloroaniline yielded only one product, [MoTp*(O)Cl](μ-O)[MoTp*(Cl)(≡NC 6H4Cl)] (2) as a red crystalline solid. The new compounds were characterized by microanalytical data, mass, IR and 1H NMR spectroscopy. The X-ray structure analysis of 1a and 1b revealed that the complexes are geometric isomers, the two chloro ligands being cis in 1a and trans in 1b. Both compounds have Mo-O-Mo linkages and nearly linear arylimido moieties.

    Synthesis, Spectroscopic Characterization and X-Ray Crystal Structures of Oxo-Bridged Oxo(haloaryl) Imido Hydrotris(3,5-Dimethylpyrazolyl)borate Molybdenum(v) Complexes
    (Taylor and Francis Ltd., 2005) Sözüer, Hikmet Işıl; Dülger İrdem, Seçkiner; Jeffery, John J.; Hamidov, Hayrullah
    Reaction of the oxomolybdenum(V) precursor [MoTp*(O)Cl2] (Tp* = hydrotris(3,5-dimethyl-1-pyrazolyl)borate) with m-fluoroaniline, H2NC6H4F, in toluene afforded the pair of geometric isomers of [MoTp*(O)Cl](μ-O)[MoTp*(Cl)(≡NC 6H4F)] (1a, cis; 1b, trans). Similarly the reaction with m-iodoaniline yielded the compound [MoTp*(O)Cl](μ-O)[MoTp*(Cl) (≡NC6H4I)] (2). This is a new synthetic method for preparing Mo-O-Mo bridged oxo(imido) molybdenum(V) species by double deprotonation of the anilines. The complexes were characterized by IR and 1H-NMR. spectroscopy, FAB mass spectrometry, elemental analysis and X-ray crystallography which revealed that the two chloro ligands are trans to each other in 1b and 2, whereas they are cis to each other in 1a. All compounds have Mo-O-Mo linkages and near linear arylimido moieties.
