    Synthesis, characterization and antioxidant study of Cu(II) and Ni(II) hydroxamic acid complexes / Syed Mohd Naqib Syed Zainal Abidin

    Synthesis, characterization and antioxidant study of Cu(II) and Ni(II) hydroxamic acid complexes / Syed Mohd Naqib Syed Zainal Abidin by Syed Zainal Abidin, Syed Mohd Naqib

    Published 2009
    “…Unfortunately, both complexes have solubility problems in dimethylsulfoxide (DMSO), chloroform, water, methanol and acetone which have restricted them for nuclear magnetic resonance (NMR) characterization. In addition, it was found that both complexes exhibit paramagnetic behavior when magnetic susceptibility characterization was performed. …”

    Synthesis, characterisation and anti-corrosion screening of Ni(ii) n-methylcyclohexyldithiocarbamate and n-ethylcyclohexyldithiocarbamate complexes / Siti Raubbah Mohd Zamri by Mohd Zamri, Siti Raubbah

    Published 2017
    “…Ni(II) N-methylcyclohexyldithiocarbamate, Ni[MeCycHexdtc]2 and Ni(II) N-ethylcyclohexyldithiocarbamates, Ni[EtCycHexdtc]2 complexes were synthesised through one-pot synthetic method at room temperature and have been characterised by using elemental analyser (CHNS), fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy, Ultraviolet-Visible (UV-Vis) spectroscopy, nuclear magnetic resonance (NMR) and molar conductivity. The stretching frequency of thioureide band, ν(C−⃛N) appeared at 1497 cm-1 for Ni[MeCycHexdtc]2 and 1484 cm-1 for Ni[EtCycHexdtc]2 while the stretching frequency of ν(C=S) has shifted to lower wavenumber as it changes from double bonding to partial bonding, ν(C−⃛S) at (1000±70 cm-1) when compared with the raw material. …”
