    Photochemical reactions of M(CO)5THF (M = Cr, Mo, W) with thio Schiff bases
    (Springer, 2008) Karahan, Senem; Kose, Pelin; Subasi, Elif; Alp, Huseyin; Temel, Hamdi
    The hitherto unknown complexes, [M-2(CO)(6)-(mu-CO)(mu-L)], [M = Cr; 1, Mo; 2, W; 3] and [M-2(CO)(6)-(mu-CO)(mu-L ')], [M = Cr; 4, Mo; 5, W; 6] have been synthesized by the photochemical reactions of photogenerated intermediate, M(CO)(5)THF (M = Cr, Mo, W) with thio Schiff base ligands, N,N '-bis(2-aminothiophenol)-1,4-bis(2-carboxaldehydephenoxy)butane (H2L) and N,N '-bis(2-aminothiophenol)- 1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane (H2L '). The complexes have been characterized by elemental analysis, LC-mass spectrometry, magnetic studies, FT-IR and H-1 NMR spectroscopy. The spectroscopic studies show that H2L and H2L ' ligands are converted to benzothiazole derivatives, L and L ' after UV irradiation and coordinated to the central metal as bridging ligands via the central azomethine nitrogen and sulphur atoms in 1-6.

    Synthesis, spectroscopic and electrochemical studies of novel transition metal complexes with N,N?-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,3-bis-(o-aminophenoxy)propane
    (Natl Inst Science Communication, 2007) Temel, Hamdi; Ilhan, Salih; Aslanoglu, Mehmet; Alp, Huseyin
    A novel Schiff base obtained by the reaction of 1,3-bis-(oaminophenoxy)propane and 2-hydroxynaphthalin-1-carbaldehyde, forms complexes with Co(II), Cu(II) and Ni(II). The Schiff base ligand and its metal complexes have been characterized by elemental analysis, microanalytical data, magnetic measurements, UV-visible, H-1 NMR, C-13 NMR and IR-spectra as well as conductance measurements. Electrochemical data show that NiL and CuL complexes undergo metal based quasi-reversible one-electron redox processes. However, metal complexes also exhibit ligand based irreversible redox waves. The electrochemical results also indicate that the electron transfer rate is higher for NiL complex than the CuL complex. Voltammetric data reveal easier electron donor properties for the NiL complex.
