    Electrical, spectroscopic and DFT studies of synthesized bridged bis (2-oxy benzylidene) hydrazine-carbonothioly-hydrazono cobalt(II)phthalocyanine
    (Elsevier Ltd, 2024) Sener, S.; Acar, N.; Dumludag, F.
    The synthesis, characterization, spectroscopic and bonding features of the new Co (II) phthalocyanine (Co-Pc) 4, containing two (2-oxy benzylidene) thiocarbohydrazone are explained. After synthesizing 2-[(3,4-dicyanophenoxy)benzylidene]-2-[(2-hyroxybenzylidene)hydrazine-1-carbothiohyrazine] phthalonitrile 3, Co-Pc 4 was obtained by chemical reaction with Co-salt in DMF, at hot and under vacuum. Compound 3 and 4 were identified by elemental analysis, UV–Vis, FT-IR, 1H NMR and Q-TOFF spectrometry. Additionally, Density Functional Theory (DFT) and Time Dependant-Density Functional Theory (TD-DFT) computations were carried out to investigate structural and electronic properties of 4. Electrical properties of the film of Co-Pc were researched as a function of frequency (40–105 Hz) at some temperatures between 295 K–523 K. DC conductivity values of the film were determined as 1.61 × 10-10 S/cm at 295 K and increased to 2.45 × 10-5 S/cm at 523 K. Activation energy value of the film was evaluated from linear part of the ln ?dc ? 1/T curve (Arrhenius plot) as 0.77 eV. It is concluded from the impedance spectroscopy measurements that increase in temperature caused to decrease the bulk resistance of the film of Co-Pc indicating semiconductor property. Additionally, since the dc conductivity of the compound Co-Pc increased 1.5 × 105 times as the temperature increased from 295 K to 523 K, the compound can be considered potential candidate as a temperature sensor. Co-Pc will be a first in the literature due to this feature. © 2023 Elsevier Ltd

    Photochemical Reactions of Metal Carbonyls [M(CO)(6) (M = Cr, Mo, W), Mn(CO)(3) C-p] With 4-Amino-3-Hydrazino-5-Mercapto-1,2,4-Triazole (AHMT) and 3-Amino-5-Mercapto-1,2,4-Triazole (AMT)
    (Taylor & Francis Inc, 2015) Sener, S.; Kul, I.; Bhat, K.
    Four new complexes of M(CO)(5)(AHMT) [M = Mo(1), Cr (2), W (3)], and Mn(CO)(3) (AHMT) (4), where AHMT is 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole have been synthesized by the photochemical reactions of metal carbonyls M(CO)(6) (M = Mo, Cr, W) and Mn(CO)(3) C-p with AHMT (1-4). In addition four more new complexes of M(CO)(5)(AMT) [M = Mo(5), Cr (6), W (7)], and Mn(CO)(3) (AHMT) (8), where AMT is 3-amino-5-mercapto-1,2,4-triazole (AMT), have been synthesized by the photochemical reactions of metal carbonyls M(CO)(6) (M = Mo, Cr, W) and Mn(CO)(3) C-p with AMT (5-8). The complexes have been characterized by elemental analysis, FT-IR, H-1 and C-13-NMR spectroscopy. The spectroscopic studies show that AHMT complexes (1-3) and AMT complexes (5-7) behave as a monodentate ligand and coordinate via ring NH donor atom to the central metal atom in M(CO)(5)(AHMT) and M(CO)(5)(AMT) where M = Mo, Cr, W, and as a tridentate ligand coordinating via imine nitrogen donor atom, amino N donor atom, and ring NH donor atom in Mn(CO)(3) (AHMT) and Mn(CO)(3) (AMT).
