    Nonlinear Inorganic Optical Materials
    (Ege Üniversitesi, 1999) Topaloğlu, Işıl
    Ticari olarak uygulamaları bulunan nonlinear optik materyallerin geliştirilmesi için yapılmakta olan çalışmalar özellikle 1980 yılından sonra artış göstermiştir. Bu amaçla incelenen sistemler arasında inorganik kristaller, yarı iletkenler, organometalik bileşikler, organik kristalin monomerler, ve delokalize $\Pi$ elektronları içeren uzun zincirli polymerler Informasyon işlemlerinde optik çevirme, telekominikasyon, optoteknoloji, ve optik frekans çevirme amaçlı olarak çok yaygın olarak kullanılmaktadır. Bu derleme makalesinde nonlinear optik özellik gösteren inorganik bileşikler hakkında kısa bilgi verilmiştir.

    Synthesis and Characterization of Two Oxo-Bridged Oxo(arylimido) [tris(3,5-Dimethylpyrazolyi)borato]molybdenum(v) Complexes and Crystal Structure of [motp*(o)ci](µ-O)[motp*(ci)(?nc6h 4ome)]
    (Springer Verlag, 2004) Topaloğlu, Işıl; Günyar, Alev; Jeffery, John C.; Hamidov, Hayrullah
    Reaction of the oxo-molybdenum(V) compound, [MoTp*(O)Cl2], [Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate] with p-methoxy and p-nitroaniline in the presence of Et3N under N2, afforded the oxo-bridged oxo(arylimido) molybdenum(V) complexes, [MoTp*(O)Cl](μ- O)[MoTp*(Cl)(≡NC6H4R)] (1, R = OMe; 2, R = NO2). The new compounds were characterized by elemental analysis, i.r., mass, and 1H-n.m.r. spectra. The single crystal X-ray crystallographic determination of [MoTp*(O)Cl](μ-O)[MoTp*(Cl) (≡NC6H4OMe)] was carried out to confirm that there is a Mo - O - Mo bridge and a near linear arylimido group in the structure.

    Preparation of Complexes Formed in the Reaction Between Dicobaltoctacarbonyl and Tetraalkyldiphosphine Disulfides, R2p(s)p(s)r2 (r = Me, Et, N-Pr, N-Bu)
    (Marcel Dekker Inc., 2000) Uğur Sarıkahya, Fadime; Şentürk, Ozan Şanlı; Topaloğlu, Işıl
    Co2(CO)8 and R2P(S)P(S)R2 (R = Me, Et, n-Pr, n-Bu) react to form the three types of cluster complexes [Co2(μ-CO)(μ4-S)(CO)4]2, (1), [Co4(CO)9(μ3-S)(μ-PR2)2] (2A)-(2D), [(2A), R = Me; (2B), R = Et; (2C), R = n-Pr; (2D), R = n-Bu] and [Co3(CO)7(μ3-S)(SPR2)] (3A)-(3D), [(3A), R = Me; (3B), R = Et; (3C), R = n-Pr; (3D), R = n-Bu]. The structure of (2A) and the disubstituted triphenylphosphine derivative of (3A) were reported previously. The complexes have been characterized by elemental analyses, FT-IR and 31P-[1H] NMR spectroscopy and mass spectrometry.

    Synthesis and Characterization of a New Mono-Molybdenated Metallo-Ligand [mo{hb(3,5-Me2c3hn2)3}(no)cl(oc 6h4pph2-P)]
    (Marcel Dekker Inc., 1999) Topaloğlu, Işıl; McCleverty, Jon A.
    The "metallo-ligands" can be considered effectively as a modified triphenylphosphine ligand, and used to generate novel transtion metal complexes in which electron-transfer and magnetism is embedded within the stable ligand framework. A new mono-molybdenated metallo-ligand was synthesized and characterized by NMR (1H and 31P-{1H}), IR and mass spectroscopy techniques as a starting material in the search for designing novel bimetallic complexes exhibiting optoelectronic properties and development of non-linear optical materials that possess commercial device applications.

    The Amido and Bisalkoxo-Complexes of [tri(3,5-Dimethylpyrazolyl)borato]molydenum Nitrosyl
    (TÜBİTAK, 1998) Topaloğlu, Işıl
    In this study, the amido nitrosyl molybdenum complex, [Mo{HM(3,5-Me2C3HN2)3}(NO)Cl(NH 2)], was prepared. This compound reacts with alocohols, yielding the bisalkoxo complexes, [Mo{HM(3,5-Me2C3HN2)3}(NO)(OR) 2] (R = Me, Et, Prn, Bun). The new complexes were analyzed by IR and 1H-NMR spectroscopy.

    Synthesis and Characterization of Amido and Amido(monoalkylamido)nitrosyl-[tris(3,5 Complexes
    (Marcel Dekker Inc., 1997) Topaloğlu, Işıl; McCleverty, Jon A.
    The chloro-amido complex [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl(NH 2)] was prepared by treating [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl 2] with an excess of ammonia. The monoalkylamido complexes [Mo{HB(3,5-Me2C3HN2)3}-(NO)(NH 2)(NHR)] (R = Me, Et, Pr-n and Bu-n) were obtained by the reaction of [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl(NH 2)] with the appropriate primary amines. The IR and 1H NMR spectra of the new complexes were investigated.

    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.
