Synthesis, Characterization and Antibacterial Activity Studies of Some Transition Metal Chelates of Mn(II), Ni(II) and Cu(II) with Schiff Base Derived from Diacetylmonoxime with Ophenylenediamine
In this study, the transition metal chelates of Mn(II), Ni(II) and Cu(II) with
Schiff base were synthesized and characterized. The elemental analysis data
showed that, the isolated chelates are in 1:1 [M:L] ratio. The molar
conductance values revealed that the chelates are none electrolyte in nature.
The results of magnetic moment measurements demonstrated that, the
chelates of Mn(II) and Cu(II) have unpaired electrons and chelates of Ni(II)
is diamagnetic. The infrared spectral data displayed the main coordination
sites of (2E, 3E)-3-((2-aminophenyl)imino)butan-2-one oxime towards
Mn(II), Ni(II) and Cu(II) ions. The electronic spectrum results of the Schiff
base ligand and its chelates suggest that the Mn(II) and Cu(II) chelates have
octahedral structure and Ni(II) chelate is square planar.
